The Top JavaScript Frameworks You Need to Learn in 2021

Are you ready to take your JavaScript skills to the next level? With so many frameworks out there, it can be hard to decide where to focus your learning efforts. That's why we've compiled a list of the top JavaScript frameworks that you need to learn in 2021.

Whether you're a beginner or an experienced developer, these frameworks can help you build better, faster, and more robust web applications. So let's dive into it!


React is one of the most popular JavaScript frameworks out there and for good reason. It's a library, not a full-blown framework, which means it's highly customizable and lightweight. Plus, its virtual DOM makes updating the user interface a breeze.

React is used by companies like Twitter, Airbnb, and Facebook, and is an essential tool for anyone looking to build modern web applications. Whether you're building a complex single-page application or a simple interactive widget, React is a must-learn framework for 2021.


Angular is another popular JavaScript framework that's perfect for building big, complex web applications. It's a full-blown framework, so it comes with everything you need to build powerful apps, including robust routing, dependency injection, and a great testing framework.

One of the benefits of using Angular is its use of TypeScript, a superset of JavaScript that adds static typing and other modern features to the language. This makes it easier to catch errors before they become issues in your application.

Angular is used by companies like Microsoft, Google, and IBM, and is a great choice for building enterprise-level applications.


Vue.js is a relatively new JavaScript framework but has quickly gained popularity among developers. It offers a great balance between the simplicity of React and the feature richness of Angular.

One of the benefits of Vue.js is its small footprint, making it easy to integrate into any project. It also has excellent documentation and a growing community that makes it easy to get help when you need it.

Vue.js is used by companies like Alibaba, Xiaomi, and Xiaomi, and is a great choice for building scalable and performant web applications.


Ember.js is a full-featured JavaScript framework that focuses on developer productivity. It comes with everything you need to build modern web applications, including routing, data management, and a great set of tools for testing and debugging.

One of the benefits of Ember.js is its use of conventions over configuration, which means you spend less time configuring your application and more time building it. It also features a strong supporting community, including an active Slack channel and Stack Overflow community.

Ember.js is used by companies like Square, LinkedIn, and Apple, and is a great choice for building ambitious web applications.


Svelte is a radical new approach to building web applications that challenges the conventional wisdom of using virtual DOMs. It compiles your code at build-time, resulting in extremely performant web applications that are smaller in size than their virtual DOM counterparts.

One of the benefits of Svelte is its simplicity, making it easy for beginners to learn and use. It's great for building small to medium-sized web applications, and can also be used in combination with other frameworks like React and Vue.js.

Svelte is used by companies like Microsoft, IBM, and The New York Times, and is a great choice for building fast, lightweight web applications.


JavaScript frameworks are an essential tool for any modern web developer. Whether you're building a small interactive widget or a large-scale enterprise application, there's a framework out there for you.

In this article, we've covered the top JavaScript frameworks that you need to learn in 2021. React, Angular, Vue.js, Ember.js, and Svelte are all excellent choices for building performant, scalable, and modern web applications.

So what are you waiting for? Get started learning one of these frameworks today and take your JavaScript skills to the next level!
