JavaScript is a multi-paradigm language. Originally, JavaScript was used only for the client side, but it has also been used as a server-side programming language. JavaScript is widely regarded as the language of the web because of this.

Although it is certainly not the only language on the web, it is well-liked enough for various frameworks to exist. Stay with us to find out what javascript frameworks are and which are in use today, and learn which one will fit your needs as a programmer who will start using frameworks.

What are JavaScript Frameworks?

A web development framework is an abstraction that allows for the selective modification of software that provides generic functionality by extra user-written code. A JavaScript framework is a JavaScript-written application that allows programmers to customize and use the functions as needed.

Frameworks offer opportunities like making apps device responsive, which makes working with JavaScript easier and more streamlined.

A JavaScript framework comprises several JavaScript libraries that produce ready-made code for everyday programming tasks.

What’s the Difference Between a JavaScript Framework and a JavaScript Library?

The distinction between a framework and a library is frequently brought up in discussions within the software industry. Although experts have said there might be some overlap, it is still important to distinguish between them.

On the other hand, a JS library is a collection of pre-written code snippets that serve more as a use-as-needed library of features than a JS framework, a complete toolset that aids in creating and organizing your website or application.

Top 10 JavaScript frameworks

Here are the top 10 JavaScript frameworks used for front-end and back-end development.
