The Best JavaScript Frameworks of 2021!

According to Stackoverflow’s 2021 Developer Survey, JavaScript has become the most used language for the eighth consecutive year, with 67.7% of respondents choosing it. The main reason why it is so popular is that JavaScript is versatile and can be used for both front-end and back-end development and testing of websites or web applications.

Use Google to search "JavaScript framework" and you will find that there are many JavaScript frameworks, each with its own advantages and uses. With so many JavaScript frameworks available for front-end, back-end development, and even testing, it can be a challenge to choose the right one for your needs.

It can be difficult to find an appropriate framework that suits your needs. This article introduces the best JavaScript frameworks in 2021. I used StateOfJS 2019, Stackoverflow Developer Survey 2021 and NPM trends to compile a list of the best JavaScript frameworks for front-end, back-end and testing, which can help you solve this problem . (This article is a front-end article)

Front-end JavaScript framework

JavaScript has been widely used in front-end development for nearly two decades. Well-known architectures like React, Vue, and Angular have attracted huge followings, and recently, some new contenders have successfully challenged these three major frameworks. The five best front-end frameworks in 2021 are as follows:

1. React.js

In the list of the best JavaScript frameworks we compiled in 2021, the number one front-end category is React.js. React.js is an open source front-end JavaScript library (not a mature framework) created in 2011 by the Facebook development team led by Jordan Walke and open sourced in June 2013. Its prototype, called "FaxJS", was first tested on the Facebook News Feed. React is arguably one of the biggest disruptors in the web development industry and a major breakthrough that shaped the web applications we see today.

React introduces a component-driven, functional, and declarative programming style for creating interactive user interfaces for primarily single-page web applications. Through the "virtual DOM", React provides very fast rendering speed by rendering only the parts that change instead of rendering the entire page. Another essential feature of React is the use of simpler JSX syntax instead of JavaScript.

Although learning React is a bit more complicated than other frameworks on this list, React has a large developer community, rich learning resources, and is widely adopted around the world.

Whether it is the Stack Overflow developer survey or the State of JS survey, React has always been at the top of the list of front-end JavaScript frameworks and has always been the most popular front-end JavaScript framework. The world's largest companies and brands, including Airbnb, Facebook, Instagram, Netflix, Twitter, WhatsApp, and more, are built with React. It wouldn’t be wrong to say that React.js is arguably the best JavaScript framework out there.

2. Vue.js

Vue.js is a lightweight, open source JavaScript framework for building creative user interfaces and high-performance single-page web applications with minimal effort.

Evan Yu first released Vue in 2014. He is a Google developer who drew inspiration from Angular and provided a simple, lightweight, and efficient alternative in the form of Vue.js. . Vue gets many features from React and Angular, but these features have been greatly improved to provide a better, easier to use, and more secure framework. Vue is the best example of this approach, providing two-way data binding as seen by Angular, and a "virtual DOM" as seen by React.

Similarly, Vue is also very flexible, allowing it to function as a complete end-to-end framework like Angular, or as a stateful view layer like React. So, the main advantage of Vue is its progressive nature, it is simpler, easier to get started, and does not impose too many restrictions to meet the needs of developers. Vue has exploded in popularity over the past two years, usurping the complex dominance of Angular and React as the best JavaScript framework. Some of the world's largest companies, such as Adobe, Apple, BMW, Louis Vuitton, and Nintendo, use Vue.

3. Angular

Ranked third in the front-end category on the list of the best JavaScript frameworks of 2021, Angular.js is Google’s open-source, script-based framework for creating client-side single-page web applications. Angular was created in 2010 by Google engineers Misko Hevery and Adam Abrons as AngularJS (or Angular 1). AngularJS was once widely known and popular, but the emergence of React exposed its serious flaws and was later forgotten. So, in 2016, AngularJS was completely rewritten from scratch and renamed Angular 2 (or simply Angular).

AngularJS (Angular 1) is inspired by React. They have changed a lot, the most important change is the shift from MVW (Model-View-Whatever) architecture to a component-oriented architecture like React. Today, Angular has become the most secure JavaScript framework for building enterprise applications; more than 1 million websites use Angular, including Google, Forbes, IBM, and Microsoft.

4. Emberjs

In the list of the best JavaScript frameworks of 2021, the fourth place in the front-end category is Ember.js. It is an open source JavaScript framework. Ember is not like other frameworks we mentioned, it uses MVVM (Model-View-ViewModel) architecture.

Ember was originally a SproutCore 2.0 framework that was renamed Ember.js by Yehuda Katz, a veteran developer considered one of the primary creators of jQuery. The most popular and basic function of Ember is the Ember command line interface, which is very powerful in its own right and is a powerful productivity tool.

Ember is one of the older JavaScript frameworks compared to React, Vue, and Svelte, but it still has a huge user base in big companies like Microsoft, LinkedIn, Netflix, and Twitch. It has many users in its customer base. Old friends like Backbone and Polymer have disappeared, but Amber continues to persevere in a passionate community.

5. Preact.js

In our list of the best JavaScript frameworks of 2021, Preact.js ranks fifth in the front-end category. It is a lightweight, fast and powerful alternative to React (it is not a complete framework). Jason Miller, a senior developer program engineer at Google, created Preact and it is used by some developers as a subset of React, with some features removed.

Preact.js is based on the same basic principles as React, a component-based approach using a virtual DOM while being fully compatible with React.

You can also use React packages without compromising speed, performance, and simplicity. If you don't need the full potential of React, most developers will use Preact during development or even switch to Preact in production. There are many big companies using Preact, including Tencent, Uber, and Lyft.

Summary

The frameworks listed in this list are far from all the frameworks required for JavaScript front-end development, but they constitute the framework currently used. The body of the class framework. As JavaScript functionality continues to evolve (through the ECMAscript process), the likelihood of framework functionality migrating to the core also increases.
