Importance Of Javascript

Importance Of Javascript

There was a time when the front-end was confined to HTML and CSS – and for a good part of history, not even CSS! Today, it will not be an exaggeration to say that the realm of front-end development companies is completely confined to JavaScript. There are different versions of JavaScript like angular, react, and node. Even though the preference of JavaScript frameworks are varying from time to time, JavaScript in general has positioned itself as an undeniable entity in the frontend development process.  

A lot of front-end development companies specialise in all of these JavaScript frameworks. Even if not for everything, there are a few companies that specialise in at least one of them, and it is what gives them the reputation of being one of the best front end development companies.

How did JavaScript take over the world of front end? What is it that made JavaScript an inevitable choice for front-end design and development? Let us read on to find out!

One For Everything :

When we think about JavaScript, we tend to think about it with a hint of monotony. However, each JavaScript has its own set of advantages and disadvantages, and it would be better to call them specific features. For example, angular JS brings the advantage of model view controller and server side scripting. This makes the content generation extremely fast. As not all correspondences have to reach the server. It is also extremely useful for making a single page application – one of the manifestations of minimalism when it comes to the application world.

It might not be an advantage with the other JavaScript frameworks but each one does have its own set of plus points making the case specific. When it comes to JavaScript it all burns down to opting for the right JavaScript keeping in mind the requirement from the customers. 

Same Old JavaScript :

No! We are not talking about how outdated the entire spectrum of JavaScript frameworks are – they are not. Instead, we are talking about the programming efficiency that it brings about by using the good old JavaScript as the programming skeleton. Although each JavaScript framework has its own signature commands and lines, the skeleton remains the same, making it extremely easy for programmers to pick it up.

That is the signature of a good programming framework – it is not that complicated things have to be achieved using complicated lines of code or by creating a completely new program script. It can just improvise upon what has been existing and still make it to be one of the best things that has ever happened to the world of design and programming. This is one of the reasons why JavaScript is being the most preferred when it comes to front end development. It is easy to pick up even if you are an amature in the field. 

Market Friendliness :

Marketing has always been a strenuous task. The hurdles that need to be crossed to overcome competition and to generate potentials is something that cannot be explained in words. The world of marketing is no longer monotonous as it once used to be – there was a time when even software had to rely on classic media like television, newspapers, and radio. Today, the avenues even within the online trailer are so wide and diverse that it is quite possible that you can market your application even without considering the television and radio.

The world of online advertising has gone a couple of notches further and it has come to a point where there is not even a need for search engines to market an app – it can entirely be done on social media.

Considering these factors, JavaScript brings their own set of advantages. Some JavaScript frameworks are not known to be search engine friendly – they take quite some time to load and are not that easily indexed by Google. However, when it comes to social media marketing, they tend to perform extremely well. Since social media has opened the gates to market any service or product in a customized manner, it is easy to reach the right set of audience with the right message at the right time.  This is what makes JavaScript a preferred choice for businesses that are competing in a highly competitive landscape where they might not stand a chance when it comes to search engines but can surely make an impact when it comes to social media marketing. 

Developer Community :

Most of the JavaScripts are supported by a dedicated developer community. These communities provide instant solutions for any query that is raised from the developer side. Every new version that hits the market is launched with an intention to make the development process a smooth experience. Since it is not a corporate setup, there is always a possibility of the community offering something new. 

Futuristic :

The tech world always embraces any concept that is future ready.  JavaScript is not an exception. JavaScript has made so much of an impact that it might be hard to think of any new framework in the near future. Even if it is the new framework is quite likely to be one of the options of JavaScript and is more likely to be backed by a big brand like how AngularJS is backed by Google and ReactJS by Facebook. 

This again ensures that the need for specialisation is not from scratch as the core of programming remains the same, making it extremely easy for you as developers to pick up the JavaScript programming for front-end design.


Front-end design and development companies have always been thanking JavaScript for making UI/UX development extremely easy. It does not just bring in aesthetics but gives the advantage of visibility.  A well planned user engagement has the true power to convert any audience into a potential lead. All we can say is, this will continue and JavaScript will stay on its rightful throne as the king of front-end design for quite some time!

Type Script Vs JavaScript

Many might know that JavaScript and Typescript are two different things. But the details of the difference are the ones most of us are not sure about. To put in simple words JavaScript is a scripting language that used to develop interactive web pages. Typescript on the other hand is a superset of JavaScript. But this is the main difference that anyone can recognize on the crust level. There is a lot more if we dig deep. In this article we will see some of the key differences between Typescript and JavaScript. 

What Is JavaScript?

JavaScript is a scripting language that is used to build or develop interactive web pages.  It runs in the web browser without the requirement of any resources. It is not just confined to browsers. It can also run on other technologies like REST APIs, XML and more. The main motive for developing JavaScript is to position itself as a complementing scripting language. More like how Visual Basic acted to C++ in the Microsoft programming language ecosystem. It was not developed for complex applications. But it is  the best for the ones with a light load. 

What is Typescript?

Typescript is a very modern age language that is used for JavaScript development. It is used to smile and a clear java code. It is also statistically compiled. It has no restrictions when it comes to browsers. The only requirement is that the browser should support ECMAscript 3 or any newer version for that matter. Typescript supports interface, optional typing and classes. 

One of the biggest advantages that the type script brings in is that the JavaScript project adopting Typescript has the capability to render robust projects. These help in easy deployment in the JavaScript application. 

Reasons To Choose JavaScript :

There are a wide range of reasons to choose JavaScript. Some of them include

  • It is specially designed for small scripts
  • It is open source
  • It has Microsoft’s Patronage
  • It runs in almost all the browsers
  • Supports classes, interfaces & modules
  • Cross compilation
  • If required it can be extended to develop large applications

It is nothing less than a wholesome package for developing interactive web pages. The features that are mentioned above are all the more enough. And it is because of this many JavaScripts play a very important role in front end development. 

Why Choose Typescripts?

Typescripts pose a lot of advantages. There are some considerable number of aspects about typescripts to choose them over the rest. Some of them are

  • The support that typescript renders to JS libraries and API documentation
  • It is a superset of JavaScript
  • There is an option to convert typescript code to plain JavaScript code. 
  • The language is optionally types
  • The code structuring is comparatively better
  • The programming techniques are object oriented
  • If there is a necessity the language extended beyond the standard decorators.

JavaScript History :

 JavaScript was created by Brendan Eich who was the programmer in Netscape Communications. Its sole purpose was to work as a Netscape Navigator. Later it became a very popular scripting tool.  A few years later it was called LiveScript. Later on it was renamed as JavaScript so that it can reflect Netscape’s support of JavaScript in its internal browser. 

Everyone should know that things did not happen overnight. JavaScript was launched in the year 1995. You will be surprised that it just took ten days to develop it. In 1996 Netscape submitted JavaScript to ECMA (European Computer Manufacturers Association) ECMAScript 2 and ECMAscript 3 were released in the year 1998 and 1999 accordingly. In the year 2005 tow big names Mozilla and Eich joined ECMA. With an aim to define a common standard library, Common JS project was launched in 2009.ECMA script 5.1 was launched in 2011 and ECMAscript 2016 was launched in 2015. The current script 2017 was launched in 2017.

History of Type Scripts :

Typescript first hit the markets in the year 2012. In the year 2013 Typescript 0.9 was released by Microsoft. At Build 2014 additional support for generic Typescript 1.0 was released. The second version of typescript compiler was launched in July 2014. It was five times faster than the old version. Support for ES 6 was released in July 2015. Features like key and lookup were added in November 2016. In March 2018 support for conditional types, and intersection types came in. 

Features of JavaScripts :

  • It is a Cross-Platform language
  • Can be used for both client side and server side
  • Easy to learn
  • It is dynamic and flexible
  • No restrictions in most of the aspects
  • Ensures strong work flow
  • Wide options for frameworks

Features of Typescript :

  • Easy maintenance
  • High productivity for developers
  • Code navigation and bug prevention
  • Wide range of features for functions
  • Supports ES6

Best JavaScript Frameworks for Frontend

It would not be a exaggeration to say that JavaScript is the language of the web.  In front end development JavaScript was initially used for client-side operations. However these days JavaScript is being used for server-side programming also. JavaScript is a multi-paradigm has positioned itself as a reliable one and become the most preferred for all front development companies. One of the important aspects of JavaScript is its frame work.

What is JS Framework?

In simple words a framework is an abstraction. A framework can be changed with the additionally written code by the user. Using the codes their functions can be changed according to the convenience of the user. They play a very important role in front end development process for designing sites and web applications.

The reason why many front end developers prefer it, is because of it makes working with JavaScript much easier and smoother. One more reason why front end development predominantly relies of JavaScript is because of device responsiveness.  Here are some of the best frameworks for JavaScript.


When Google offers something it is bound to be exceptional and Angular JS is not an exception. This open source JavaScript is considered to be the favorite for many front end developers. When it comes to developing Single Page Application, Angular JS is a clear winner. The HTML is extended into the application and data binding is performed by interpreting the attributes.

React JS

It would not be an understatement to say that React JS is one of the favorites for front end developers. If you want to build an application or a page with reactive approach, React JS would be the ideal choice. React brought in something new to front end development as it had a unique way of approaching things. Some of the basic aspects that you need to master to use React are JSX, component based architecture, and single direction data flow. Flux implements the single direction data flow.


Vue JS was developed in the year 2016. Even though it is the new kid in the block Vue JS has a considerable penetration when it comes to front end development. Within a short span of time Vue JS has a proved its worth to all the front end developers in the world. It offers a wide range of features. Some of it that deserves a special mention dual integration mode. It comes in handy while creating a high-end SPA or even a single page application for that matter. It is one of the most preferred when it comes to cross platform development.

Ember JS

Ember JS has a diverse application potential. Its foray into the market was in the year 2015. One of the important aspects of Ember JS is that it supports two ay data binding system. Hence handling complicated User Interface will not be an issue. It is a boon for professionals who are involved in UI/UX process. Many popular sites were developed using Ember.js. To name a few LinkedIn, Nordstorm and a lot more.


Meteor is quiet popular as it has the potential to handle all the significant portions of software development. Meteor is majorly used to carry out some of the important processes in backend development, database management and a lot more. In terms of front end development it is one of the best when it comes to rendering.


Mithril JavaScript is one of the best when it comes to developing single page application. The implementation of the framework is very simple because there is no derived function from abase class. The size is also very small which is less than 8kb. It is very fast which is one of the notable aspects when it comes to front end development. There are some features that are very similar to react js.

Node JS

Node JS works on cross platform and is a server side JavaScript. The event driven architecture with is capable of driving asynchronous I/O. As it works in the JavaScript Runtime environment it has very similar prosperities of JAVA. Some of them include threading, loops, packages, and forming.


When it comes to Google and JavaScript, the first thing that hits our mind is Angular. But Polymer is also from Google. There is one segment of front end development that Polymer specializes in. There are certain elements in website that can be executed with Polymer with very low levels of complexity. It supports both one-way and two-way data binding. This has paved way for application in diverse areas.


Aurelia framework is one of the latest of JavaScript. One of the major applications of Aurelia is implementing interfaces. With Aurelia better and robust websites can be developed. The framework is capable of extending HTML for various purposes, which also includes data binding. It modern architecture is something that deserves a very special mention because of interpretation server-side and client-side at a time.


Backbone JavaScript is one of the most popular in front end development. Comparing to most of the JavaScripts it is easy to understand and learn. It is majorly used for developing single page applications. With Backbone complex tasks can be achieved easily with simple codes. It is because all the server side functions must flow through the API.

Best Javascript for Beginners

Ever since the beginning of technology, there has always been a quest to complicate things. These complications result in better utility and every line of code has its own importance that cannot be replaced. There are developers who are on a constant request to update their knowledge so that they can build more robust applications that are rich in features.

However, sometimes, it is forgotten that a framework needs to be as simple as possible to entice and attract beginners and novice quarters into using that framework. This alone is going to result in a big stream of new developers embracing the framework. In that respect, we have given below, some of the easiest JavaScript frameworks that you can use to create your app or your web page.

It is quite known that JavaScripts like Angular, Aurelia, and Ember stand among the most popular. As much as they are popular, they are also known for being the hardest to learn and to optimize.

React and Vue stand somewhere in the middle sandwiched between being extremely easy to learn and extremely difficult to learn. The latter is known for being progressive where it starts as a simple thing to learn but becomes increasingly complicated as you add features to its functionality. React, on the other hand, is known for the syntax that resembles J query. Inclusion of the J query like syntax only results in an increased complexity of the code, making it extremely difficult for beginners to master all the facets of this JavaScript.

In addition to that, both the above-mentioned JavaScript platforms have a problem of architecture bloating. Both of them have pure view libraries. It implies that when state management, state flower, and rotors are added, the complexity starts to increase exponentially. Therefore, it might not be a good idea for beginners to start with React or Cue.

That leaves us with one of the most unsung and amazing JavaScript is created. There are good chances that you might not have even heard the name. We are talking about this JavaScript called Mithril. Mithril’s API is quite similar to that of React and Vue but it has everything that is essential fto create a single page application. The components also include router and connection library. These are the components that complicate the coding exercise in React and Vue.

Mithril’s documentation is one of the best advantages brought to amateur coders. Instead of forcing implementations on the developer, it puts the reliance on the developers themselves.

Above everything, what makes Mithril one of the best platforms is the number of lines in the CodeBase. Vue has over 11,000 lines of code in its base. Every line of code is a representation of complexity in learning. It also implies that every line should be understood to understand and unravel the workings of the JavaScript and it’s functionalities.

Javascript and SEO

Ever since its introduction in 1995, JavaScript has been constantly transforming the way in which people interacted with the web. It has been considered a point of Blaaze when it comes to engaging users in the most interactive fashion. This has come in as a massive advantage for people who come into the website through direct input on the browser address bar or from sources of referral traffic like social media. However, when it comes to performance on search engines, JavaScript has always taken a backseat.

It is indeed a thing of wonder because one of the most prominent JavaScript frameworks, Angular JS is the brainchild of Google, and the search engine giant has been instrumental in creating such a robust and flexible framework for the development of single page application. There is no point in pondering over why something has not happened. A better way would be to find out the ways to circumvent this problem and make JavaScript applications friendly for search queries.

To understand how JavaScript search engine optimisation works, it is important to understand what exactly is search optimisation and how does the entire process happen.

What is SEO?

Search engine optimisation is the art and science of ranking your web page on the top of the search results for relevant searches on search engines like Google and Bing. All the search engines use a combination of techniques to determine which web page should be listed first for a particular search query. There are a lot of parameters including but not limited to the content, the code, and the number of links from external sites that point to one particular site. The external links acts as democratic factors in determining the value and popularity of a page.

How Does It Happen?

When a new page is created, the search engine spiders crawl the web page and take a note of the URL and the code. The code is then processed and it is stored as meta data which contains information about the theme of the content on the web page. After all the information is taken, it is indexed on servers, ready to be presented as a search results.

The JavaScript Jinx

There is one challenge with JavaScript in this entire process! As we all may have known, most of the JavaScript frameworks are designed to render on the client side. It means that the page might not have a lot of relevant information when it first loads. The relevant information is decided to appear only when the user interacts with the page. Therefore, when search engine spiders crawl the page, they might not be able to get a complete hang of what exactly is there on the page. The challenge here is to ensure that Google gets the information about what the pages about, while at the same time, not compromising on the quality of interaction with the user. The solution to this challenge can be addressed by server side or pre-rendering.

The Way Out

Pre-rendering basically tells search engines that this is the content that will be displayed to the user after a certain pattern of interaction takes place. In essence, you are revealing to the search engine what the user is likely to experience. This might not affect the user in anyway! You retain the way in which a user interacts with your page but at the same time, inform search engines about what the pages!

The basics

Even in all the JavaScript, it cannot be denied that HTML can seamlessly integrate with the JavaScript framework. Therefore, if you can write the right titles and meta descriptions, it has a great possibility of being picked up by the search engine spiders and it can greatly helps in fixing the ranks for your web page. In addition to that, using unique snippets also helps in bringing quality visits to the web page.

It is quite known that the heaviness of the page also contributes negatively when it comes to the performance on search engines. Therefore, it is important to keep your web page as light as possible, irrespective of the technology that you have used to build your mobile app.


Adding a splash of pessimism, the crudest form of an innovation is when something cannot be accommodated! That is the case with JavaScript and it’s frameworks. It could possibly be that search engines are not that evolved to find out what exactly JavaScript framework applications intended to. There is quite a possibility that in the near future, JavaScript could be the order of the day and for all you know, it could be the most preferred to technology by search engines.

Server Side Javascript

Server-side web frameworks (a.k.a. “web application frameworks”) are software frameworks that make it easier to write, maintain and scale web applications. They provide tools and libraries that simplify common web development tasks, including routing URLs to appropriate handlers, interacting with databases, supporting sessions and user authorization, formatting output (e.g. HTML, JSON, XML), and improving security against web attacks.

The next section provides a bit more detail about how web frameworks can ease web application development. We then explain some of the criteria you can use for choosing a web framework, and then list some of your options.

What can a web framework do for you?

Web frameworks provide tools and libraries to simplify common web development operations. You don’t have to use a server-side web framework, but it is strongly advised — it will make your life a lot easier.

This section discusses some of the functionality that is often provided by web frameworks (not every framework will necessarily provide all of these features!).

Work directly with HTTP requests and responses

As we saw in the last article, web servers and browsers communicate via the HTTP protocol — servers wait for HTTP requests from the browser and then return information in HTTP responses. Web frameworks allow you to write simplified syntax that will generate server-side code to work with these requests and responses. This means that you will have an easier job, interacting with easier, higher-level code rather than lower level networking primitives.

Most sites will provide a number of different resources, accessible through distinct URLs. Handling these all in one function would be hard to maintain, so web frameworks provide simple mechanisms to map URL patterns to specific handler functions. This approach also has benefits in terms of maintenance, because you can change the URL used to deliver a particular feature without having to change the underlying code.

Data can be encoded in an HTTP request in a number of ways. An HTTP GET request to get files or data from the server may encode what data is required in URL parameters or within the URL structure. An HTTP POST request to update a resource on the server will instead include the update information as “POST data” within the body of the request. The HTTP request may also include information about the current session or user in a client-side cookie.

Websites use databases to store information both to be shared with users, and about users. Web frameworks often provide a database layer that abstracts database read, write, query, and delete operations. This abstraction layer is referred to as an Object-Relational Mapper (ORM).

Using an ORM has two benefits:

You can replace the underlying database without necessarily needing to change the code that uses it. This allows developers to optimize for the characteristics of different databases based on their usage.

Basic validation of data can be implemented within the framework. This makes it easier and safer to check that data is stored in the correct type of database field, has the correct format (e.g. an email address), and isn’t malicious in any way (crackers can use certain patterns of code to do bad things such as deleting database records).

Web frameworks often provide templating systems. These allow you to specify the structure of an output document, using placeholders for data that will be added when a page is generated. Templates are often used to create HTML, but can also create other types of document.

Web frameworks often provide a mechanism to make it easy to generate other formats from stored data, including JSON and XML.

Top Javascript Frameworks

As modern web browsers become more powerful, the desire to build full-blown web applications using JavaScript has become increasingly popular. Luckily, the complexity of this programming language has brought with it a range of tools to help custom software developers take full advantage.

Few custom software developers start with a blank screen when building a new app in JavaScript. That’s why, over the last few years, a number of frameworks have been devised that enable people to build deeply functional web applications without having to spend countless hours manually writing routine code.

MVC frameworks can be implemented quickly and combined with manually-written code that introduces the all-important business logic (the stuff that determines the real-world business rules for such software).

What is A JavaScript MVC Framework?

The Model-View-Controller pattern helps developers organise their code in an uncluttered, approachable manner. The three elements can be very simply described as follows:

Model. This represents the underlying structure of data within an application.

View. The user interface – everything that can be seen and interacted with on screen.

Controller. This handles the input from any View element that is interacted with by the user and manipulates the Model accordingly.

By dividing any piece of software into the three interconnected parts above, developers can focus on each element independently while always being mindful of its effect on the other areas of the app.

The Best JavaScript MVC Frameworks

HTML Ajax apps are becoming increasingly sophisticated, but developers need assistance in taking full advantage of modern web browsers. Thankfully, there are a vast range of JavaScript MVC frameworks available. Below, we’ve picked out 10 of the best.

1. Kendo

A great framework for mobile and web app development, consisting of three widgets: UI Web (everything you need to build a modern website), UI Mobile (offers the ability to build mobile web apps that could be mistaken for native apps) and UI DataVis (enables developers to implement beautiful user-facing visualisation of data and reports).

2. Sencha Touch

Sencha is a great user interface JavaScript library that is built specifically for mobile web apps and enables developers to create user experiences that feel like native applications.

3. jQuery Mobile

A cross-platform mobile JavaScript framework, jQuery Mobile is designed to enhance and simplify web app development by integrating HTML5, jQuery, CSS and the jQuery UI into one, single framework. It is robust and satisfyingly well-organised.

4. AngularJS

Considered by many to be the ‘big daddy’ of JavaScript frameworks, due to the fact it was developed by Google. There is a huge developer community behind AngularJS and it excels particularly in supercharging HTML code thanks to its ability to aid the construction of dynamic user interfaces.

5. Ember

Originally released in 2011, Ember takes cues from Angular when it comes to the ability to create dynamic user-facing elements for web apps. Like Google’s framework, Ember can update the View when the Model changes and vice versa, keeping the mechanics of apps perfectly in sync.

6. Backbone

Used by Pinterest, Walmart and Delicious, the Backbone framework is purposefully simple, easy to learn and light on its feet when it comes to deployment. Many developers love the ease with which Backbone.js can be slotted into any project.

7. Meteor

A full end-to-end solution for developing complete web applications purely in JavaScript. Meteor includes tools for everything from the pretty front-end stuff to the functional back end database management and business logic.

8. React

Facebook and Instagram rely on the React JavaScript framework due to its ability to build large applications that are dynamic and can be vastly scaled. React is at its best when rendering complex user interfaces and is rapidly becoming the fastest growing JavaScript framework of the modern age.

9. Aurelia

A relatively young framework, Aurelia was originally released in January 2015 and can trace its roots back to AngularJS. It is notable for its vast collection of small libraries from which developers can pick and choose without having to implement the entire framework.

10. Polymer

Another Google invention, the Polymer framework extends the capabilities of HTML code by using web components. It means that standard HTML5 elements can be customised (for example, <audio> could become <my-audio>).

Top Javascript MVC Framework

Model view controller or MVC has elevated the utility of JavaScript front-end frameworks. JavaScript front-end frameworks minimise the number of communications between the client side and the server side by executing reactions to user actions on the client side itself. It makes use of asynchronous JavaScript across XML, commonly abbreviated as Ajax.

All the responsiveness is governed by logic. The number of logical statements that need to be executed on the client side is directly proportional to the intensity of interaction on the web page. The volume of the code base grows larger and becomes increasingly difficult to maintain. To counter this, developers introduced model view controller or MVCs. These MVCs deliver a considerable increase in productivity and in the magnitude of ease in maintaining the code.

There are a lot of MVCs available in the market. We have compiled below, a list of popular MVCs that are commonly used across multiple JavaScript frameworks

Backbone.js – it might not be as popular as its counterparts but it does provide models with the keyvalue binding and custom events. It also provides connections and connects it all to your existing API.

AngularJS – by a considerable distance, it is the most popular MVC. It is nothing more than a toolset based on augmenting the vocabulary of HTML for creating your web application.

Knockout – it aims to simplify the user interface of JavaScript by implementing the model view view model (MVVM).

Maria – it might seem like quite a strange name for JavaScript framework. It is based on the original definition of a model view controller as it was used in SmallTalk.

Agility.js – this MVC helps developers right browser codes that are both maintainable and reusable. It does not involve infrastructural overheads found in other MVC libraries.

Spine – it is a lightweight framework which is beginner friendly with perfect documentation. This makes spine a favourite among novice developers.

Ember.js – this MVC provide templates written and attempted language called Handlebars. It can define the views, controllers, models and router.

Sammy.js – JavaScript does not limit itself to framework but it can also be used to develop applications. Sammy.js is a small JavaScript framework that is designed to provide the basic infrastructure for developing JavaScript apps.

Stapes.js – today, no technology can exist if it does not cater to mobiles. This is a tiny framework that aims to fit and integrate into an existing code base. The tiny size makes it ideal for mobile development.

Epitome – it is a MVC framework developed exclusively for MooTools.

rAppid.js – some of the classics cannot be forgotten. This framework lets you encase complexity into specific components that can be used like HTML elements.


It is quite evident that MVCs are here to stay and dominate the world of JavaScript. MVCs are the strongest representations of how an established technology will find its way out to ensure user friendliness without compromising on what made the technology awesome in the first place!
