Best JavaScript Frameworks To Build Your Next App

Looking to build a new feature-rich JavaScript app? These days websites are full applications that run in the browser, and you’ll need a solid foundation to build them on. In this article we’ll compare some of the most popular JavaScript frameworks and give some examples of sites that use them.


React is the most popular JavaScript library that is not a UI framework (e.g. Bootstrap, Angular). It has been developed by Facebook and it has a relatively small amount of developers, but has become the standard library for building large-scale frontend web applications. It provides a declarative component-based approach and is based on an event-driven rendering system, meaning that state changes will be rerendered, and events such as clicks will also cause the view to update.

It’s easy to use: The whole library is built around two concepts: “Components” and “Events”

A Component is a class that wraps a set of functionality and accepts data from parent components (it is a “pure” component)

An Event is a way to communicate between components: for example, click, onChange, etc… (it is a “bound” component)

With React, components are reusable. You can also use reusable components inside a component that is your main application. The reason behind this is to avoid the need to write “rendering” code multiple times.

Some sites that use React include the dating site Fling and Reddit.


Preact is the successor of React and is an open-source JavaScript library that allows you to use declarative, unopinionated, and easy-to-use libraries to build modern user interfaces. It has been inspired by React.

Preact provides a declarative component-based approach, but it is more powerful than React and is optimized to be performant, particularly on mobile.

Some sites that use Preact include Groupon and Uber.


Vue is an opinionated JavaScript framework that allows you to use reactive, unopinionated, easy-to-use libraries to build modern user interfaces. It is also known as “the JavaScript framework for power users”, which is very fitting, because it offers a number of features and benefits.

It’s easy to use, it only has one file that is included in the page, and you can also add as much or as little code as you want (like Vue.js does, with “vue” and “data”).

It provides a simple and easy way to add data to the app using data-v- attributes.

Some sites that use Vue.js include 9gag and Gitlab.


Backbone is one of the first JavaScript libraries that was created to help develop mobile apps. It was created by Backbone.js and Twitter. It provides an easy way to create single-page applications. It provides a clean interface for creating models, views, and collections.

The collections that are built are models that help to group models together. Models have a lot of features that are really useful to have in a modern app. You can add views and models to views and models using the “model.setView(view)”. You can also add more views to the same view. This is all provided by the model and the view. Also, views have a view.el property, which is a reference to the view’s container.

Some sites that use Backbone.js include Quora, Twitter, and Tumblr.

Angular 2

Angular 2 is an open-source JavaScript framework. It’s a successor to Angular 1. It was built to improve the performance, modularity, and maintainability of Angular 1. It’s easy to use and it makes you focus on writing good code and not worry about the framework. Angular 2 uses TypeScript, which is a superset of JavaScript. It’s a statically typed language, meaning that variables have a fixed type and you can’t assign random things to it. TypeScript also has strict null checking.

Some sites that use Angular 2 include Medium and Facebook.

Which framework is right for you?

All frameworks have advantages and disadvantages. If you’re planning to build a single page application or are a seasoned developer who already uses a JavaScript framework, it’s not as hard to choose a framework. For newbie developers, we recommend the framework that makes them more comfortable.

We also suggest that you try a couple of frameworks, as it’s easy to get stuck in a certain paradigm.

If you are building a single-page application or you are a seasoned developer, React seems to be the right framework for you. If you are building a React site, we recommend you try React and Redux together.

I have always used Angular 1 for all of my projects. I was going to use React for one project recently but have a concern that it would be difficult to maintain in the long run. I use Angular 2 for everything else. Ultimately, all of the major JavaScript libraries are a good choice, and you should just pick one and get started.
