JavaScript is the most widely used language in the field of development over the world. For more than 25 years JavaScript Frameworks have been driving the web. But JavaScript code has been gently processed in JavaScript frameworks at least over the last decade.

In this article, I will elaborate on JavaScript frameworks and the uses of JavaScript programming languages. Frameworks are JavaScript containers that empower the language to achieve its best with minimal or no configuration.

JavaScript is one of the most popular languages and is currently a choice for both front and backend web development. Also, in the middle of a JavaScript framework, you’re probably going to choose quite soon. 

 JavaScript Frameworks: Frameworks provide the basic platform for constructing JavaScript apps for developers. This saves developers the work to start with a functional basis to get things going from scratch.  This base includes a set of code libraries in the instance of JavaScript. The libraries are compiling code for the specific application type you can work on. The framework will essentially determine the structure of the program on its own.  A different function is used in each JavaScript framework. For web development, JavaScript is a firm choice and many of its structures are based around this enterprise.

Following are the top JavaScript frameworks used these days:

What do JavaScript Frameworks do?

It can take some effort to develop web apps and websites from scratch. You might think literally of the term framework. Houses are likewise based on frames as a skeleton to support and form an external structure. The frameworks of software do the same.

Uses of JavaScript Programming Language  

JavaScript is a simple object-driven programming language used in the scripting of web pages by a number of websites. This is an interpretation, comprehensive language of programming. When applied to an HTML document JavaScript allows dynamic Website Interactivity.

JavaScript empowers users to construct modern web-based applications without reloading a page. JavaScript is often used to refresh a DOM API user interface by changing HTML and CSS dynamically. It is used extensively in online applications. The following are some uses of JavaScript Programming Language.

1. Web Applications: As a day-to-day development of browsers, JavaScript is becoming more popular for the development of strong Web applications. Taking the Google Maps example, we can comprehend this. The user needs only to click and drag the mouse with Maps, the details can be seen with a single click. Behind these concepts, JavaScript is used.

2. Web Development: For developing web pages, JavaScript is often implemented. It enables us to add dynamics to the website and to provide specific website features. It is used mostly for validation reasons on websites. JavaScript enables us to do complicated tasks and allows users to engage with websites. You can also load the content into a document using JavaScript without downloading the web page.

3. Mobile Applications: Mobile phones are widely utilized for Internet access. We can also develop a non-web context application with JavaScript. It is a robust tool for designing mobile applications through features and the use of JavaScript. The JavaScript framework is frequently employed in the creation of mobile apps. We can design mobile apps for several operating systems with React Native. React Native has been proven one of the top JavaScript frameworks for mobile applications. For iOS and Android operating systems, we do not need to write different codes. We just have to build and run it on several systems at once.

4. Games: For creating games, JavaScript is commonly used. It has different libraries and game-building frameworks. Either a 2D or a 3D game. JavaScript engines like PhysicsJS and Pixi.js enable us to build a web game. The WebGL, a JavaScript API, can also be used to render 2D and 3D images on your browsers. We have the option of running the images. 

5. Presentations:  We can also develop presentations as a website with JavaScript. The web-based slide decks can be used by libraries such as RevealJ and BespokeJS. They’re easier to operate, so in a short time, we can easily do something wonderful. With the use of HTML, RevealJS makes interactive and elegant slideshows. These lectures function with mobile devices and tablets very well. All CSS color formats are also supported. The BespokeJS consists of a range of animated bullet lists, responsive sizes, and features.

6. Server Applications: Many web apps have their server-side. For content generation and handling of HTTP requests, JavaScript is required. You can also run JavaScript over NodeJS on the servers. NodeJS provides an environment with the capabilities to run JavaScript on the server.

7. Web Servers: You can use NodeJS to develop a web server. NodeJS is event-driven and does not expect the prior call to respond. The NodeJS servers are quick and do not need buffering or transferring data chunks.  

Using the createServer() method you may leverage the HTTP module to create the server. This is when someone tries to access port 8080. The HTTP server should show HTML in the HTTP header as a response.

Lets’ see the Pros and Cons of Top JavaScript Frameworks:

1. Angular JS: AngularJS is a JavaScript MVC client-side framework for creating dynamic web applications. AngularJS began as a Google project, but it is now an open-source framework. There is no need to gain knowledge of another syntax or language because AngularJS is entirely based on HTML and JavaScript.


  • The data syncing the model with the view.
  • Model changes are seen in the view instantaneously.
  • The use of guidelines: This allows developers to use features and to generate instructions for modification.
  • Injection of dependence: a mechanism that depends on software components.
  • It makes managing and using it easier. It has an architecture based on an MVVM: This Architecture for the Model-View-Model allows us to distinguish data from view.
  • Aid to the handling of applications.


  • There are many decisions where it does not support JavaScript.
  • To use angular, a developer needs to know about MVC.

2. React Native: Web developers can now create mobile applications which feel and look truly “native,” all while using a JavaScript library they are already familiar with. React make it simple to develop at the same time for Android and iOS because most of the code we write can be shared across the platform.


  • It turns the real DOM into a virtual DOM.
  • It assists developers to create better codes and make better UI.
  • Data in it is unidirectional.
  • Parent elements are not affected by child elements.
  • Increase reusability of the code and use JSX.


  • It is a little difficult to learn and comprehend
  • It is a framework with poor documentation

3. Vue JS: With the help of Vue.js, we can create UIs(User Interfaces) and SPAs(Single-page Applications) because it is a progressive JavaScript framework. Its a very easy framework and we can make web applications in it with little knowledge of HTML, CSS, and JavaScript. 


  • Vue JS uses HTML templates
  • Data is gathered with the DOM
  • The data is transferred in Bi-Directional
  • Vue JS is more Reactive than others
  • It is simple to integrate with other frameworks.


  • It overcomplicates the developer by its flexibility.
  • It is the latest library and the developers are fewer.

4. Ember JS: Ember Js is a JavaScript platform. It is one framework that is used to create a single web application. With the help of idioms, best practices, and patterns, it will create a fantastic one-page web application connected with others. It is also scalable and has ecosystem patterns via the framework.


  • Potent add-ons
  • Ember CLI
  • Convention over configuration
  • Stability sans stagnation
  • Community
  • Ember Octane


  • Tough to learn
  • Highly opinionated
  • Sluggishness in Popularity

5. Mithril: Another framework of JS, Mithril, is one JS that is quick and used to get work done effectively. Another quality of this framework is the size of it, and that is less than 10 KB. It also implements routing and XHR utilities.


  • Lightweight
  • Faster than React
  • Works with ES6
  • Very active development
  • Intelligent auto-redrawing system
  • Flux compatible
  • Small Learning Curve


  • Virtual Dom

6. Meteor: Meteor is another JavaScript framework that is isomorphic and primarily used for websites. With the help of NODE JS, you can complete your project quickly, as prototyping. Node JS also helps create cross-platform apps which help to build Android, IOS, and Web versions. Another excellent quality of automatically data updating when you connect with MongoDB


  • It is easy to start and to get a prototype out to end-users quickly.
  • Hot code push
  • Full-stack reactivity.
  • Helpful for real-time applications.
  • Allows you to build an MVP


  • Auto-bundling
  • Auto-optimizing build system
  • Problem with the speed
  • Unpredictable in development

7. Node JS: One of the most famous Java Frameworks is Node JS. With the help of an event-driven, non-blocking I/O model, it will make Node JS Lightweight and practical. The ecosystem package, nmp, is the most extensive open-source ecosystem library in the world.


  • Asynchronous event-driven IO helps concurrent request handling. Easy to learn.
  • Both the server and client sides should use the same piece of code.
  • NPM, the Node packaged modules are huge and still growing.
  • An active and Vibrant Community
  • Stream big files


  • Doesn’t provide scalability
  • Using a relational database is a burning
  • Nested callback.
  • Not Suited for CPU-intensive tasks

8. Polymer: Polymer, an open-source Javascript library, is used for creating website applications with the help of web components. Google developers and GitHub contributors generate the language. In addition, Google is implementing the Modern design principle with the help of its framework Material Design. 


  • Web components
  • Material design
  • Backed by Google
  • Data Binding
  • Open-source
  • Designer friendly. HTML concepts


  • We need to try harder to make components in every browser.
  • The different browser works with Shadow DOM.
  • Slow in Performance on Mobile

9. Next JS: Next, JS is also a JavaScript framework used to create super fast and highly user-friendly static websites. Then, with the help of React, you also make a web application. Static and dynamic have now merged as a result of automatic static optimization. It is primarily used to create a hybrid application.


  • Automatic server rendering and code splitting
  • Easy setup
  • Static site generator
  • Simple deployment
  • Frictionless development
  • Incremental static regeneration
  • Filesystem as an API
  • Isomorphic React applications
  • Testing
