According to a survey made by Stack Overflow, JavaScript is considered the most famous programming language among developers for eight years in a row. It is used in both front-end and back-end applications. Therefore, It is popular among developers. That's the reason most huge companies are currently using JavaScript Frameworks.

What is a Framework

Let's start by a simple example to explain the concept of a Framework. You have a group of bricks. These bricks are the Framework. They can be used to build a house. The bricks have certain dimensions that you have to work with. You can build houses of different sizes and shapes but you can't manufacture a car or an airplane with it. You need to search for a different framework for that. JavaScript Framework provides a certain set of rules that can be used by any developer to make complex applications faster and efficient. It is easier than building an application from scratch. JavaScript is used for both client and server side so there are multiple frameworks to work with.

What is the difference between Framework and a Library

Framework is a full toolset that helps organize your website or application, while on the other side library is a collection of code functions that provide needed library of features and don't help in shaping your application. The Three main types of Frameworks in JavaScript are: Front-end Frameworks, Back-end Frameworks and Testing Frameworks.

Difference between frontend, backend and testing

  • Front-end: It is the programming which focuses mainly on the client side (visual elements of a website that a user will interact with).
  • Back-end: It is the programming which focuses mainly on the server side (side of a website users can't see). Front-end and Back-end work together to create a dynamic website that allows users to apply any interactive activities you might take part in while using the website.
  • Testing: As the name says, testing is used to ensure the functionality correctness of the website.

Discussion of most popular JavaScript Frameworks

Front-end Frameworks


React framework
  • Developer: It is developed by Facebook.
  • Functionality: It helps in building interactive user interfaces. In addition, it provides a component system where code is written once and can be reused in different parts.
  • In comparison to other Frameworks: It is considered number one in terms of some of the most important factors, like developer satisfaction, interest, usage, stability, and popularity.
  • Popular companies that are built using React: Twitter, Airbnb, New Your Times and Instagram.

  • Functionality: It is more than just a framework but a platform used for building dynamic web applications. It has all the functionalities and features that can be needed by a front-end application.
  • In Comparison to other Frameworks: It was popular with React at the beginning but popularity decreased over years due to lack of flexibility and requirement to be familiar with two programming languages. As angular applications are written in Typescript.
  • Popular companies that are built using Angular: Guardian, IBM, Udacity and YouTube.


Screen of an VUE.js framework
  • Developer: It is developed by Evan You, an ex-Google employee. Currently it is maintained by a group of core team members and open source collaborators.
  • Functionality: It is more flexible. It can be used as a plug-and-play library. Also, It has a lot of helper tools that can be used for creating efficient, fast and progressive single page Application.
  • In Comparison to other Frameworks: It is ranked among the top 3 Frameworks. This is due to its simplicity, small size and it is much easier to set up. That's the reason it outraged the performance of a lot of competitors.
