What Is JavaScript Framework?


What Is JavaScript Framework?

In brief, JavaScript frameworks are a collection of libraries containing code written in JavaScript, making life a lot easier for software developers. Each JavaScript framework offers pre-built codes for different areas and different purposes in software development, saving time for the developer.

JavaScript frameworks

JavaScript frameworks provide structure for your code, so in that sense, they’re pretty essential to your programming. There are many useful JavaScript frameworks that developers regularly use, and we will cover some of these in this article. A JavaScript framework provides a blueprint, so you have a guide to follow rather than having to start coding your website from scratch. 

Most frameworks are open-source, meaning they are constantly being improved by the community that uses them, so they are always up to date. They are by no means set in stone either; you are free to tweak the framework you choose to suit your own website or application.

Why use a JavaScript framework?

Developers created JavaScript frameworks to make life easier for themselves. They allow programmers to use the most up-to-date JavaScript features and tools without having to go through the arduous task of coding them from scratch by themselves. 

These frameworks are templates that provide a foundation for software applications. It collects shared resources like libraries, reference documents, images and more and packages them for developers to use. With these frameworks, programmers can add better functionality and more to a web page and website. 

Popular JavaScript Framework libraries

There are many JavaScript framework libraries available for software developers to work with. Each is unique in their own way, while many will do some of the same things, but often, differently.


AngularJS is an open-source framework that came into being in October 2010 and is the oldest available. It’s a good one to choose when you’re thinking about which framework would be best to go for; brilliantly, it is supported by Google! There are even apps built into cars made by General Motors that have been developed in Angular – it has emerged as a bit of a market leader in JavaScript frameworks. Google’s lead Angular developer, Igor Minar, believes that Angular is the most widely used framework because it, more so than others, encourages regular updates and developments.


React.js is a library that Facebook supports. The aim of React when Facebook originally built it was to build a richer and more responsive user experience. It’s a real time-saver that cuts down development time for its users. It’s now one of the most popular libraries in the world and is used by companies like Meta, the BBC, PayPal and more.


Vue is really good for front-end lighter projects. It’s also really good for developers who need to get a project over the line quickly. Many say that this is easier to learn than the likes of Angular because it uses an HTML-based syntax.


Bootstrap was created in 2011 by Twitter. It is a powerful front-end open-source framework that includes pre-built HTML, CSS and JavaScript components for building mobile-first responsive websites. This is great for ensuring your information is accessible from any device.


Backbone is another JavaScript framework. However, its popularity has waned over the last few years. It followed Angular onto the JavaScript framework scene in 2010, so it’s around almost as long. Backbone was the framework of choice for internet giants such as Twitter and LinkedIn, so, again, it’s not a bad option to choose from. It was also the framework used to build music apps like Soundcloud and Pandora.


Ember came into existence in 2011. What’s keeping Ember’s flame alive is the speed at which websites that use it load. “They feel like normal websites. They’re just much faster than what you are used to”, says Ember co-creator Tom Dale.


Node.js is an open-source backend framework that is used to create scalable network applications. Node runs the V8 JavaScript engine in Google Chrome and is great for use in real-time web applications. 

Other JavaScript frameworks

Of course, there are many other JavaScript frameworks, including 

HTML, CSS and JavaScript

Before you start working with JavaScript frameworks, it’s essential to have learned HTML, CSS and JavaScript. If you want to learn some of the basics for free, then register for our free 5 Day Coding Challenge through the form below.
