Which JS Framework Is Best for Front End In 2021?

Which JS Framework Is Best

If backend development is the backbone of an application, Frontend development is the face of the application. Few years earlier, websites and mobile apps were made of simple static text site with limited interactive features with other websites and apps, whatever innovation was used to done by minimal animation that hovered on the screen. This was the age of HTML and CSS.

But today, the evolution of JavaScript Frameworks has changed the scenario. Today's mobile and web applications play videos, chat with users, fill out forms, interact with other apps, and do almost everything that makes it best for users to remain consistent in performance.

JavaScript is undisputedly the most renowned language used by developers that gives a high prestige among other frontend development tools. 

Why JavaScript?

 

Used by Every Platform

JavaScript framework is used across a wide range of different platforms such as React, Angular, Node, Vue, and on Browser, Mobile, IoT, Desktop Apps and a lot more.

Best Foundational Language

Learning Java language means learning every language. It is the foundation of all other languages that is used today in modern development. So, once you learn JavaScript, you don't have to put extra effort on learning other languages.

Manage Complexity

JavaScript is helpful in building complex websites like PayPal, Netflix, and LinkedIn.

Faster Deployment

JavaScript comes with the option of a feedback loop. As this is built on browser, it allows developers to run the code and get instant results making deployment faster.

For its ranging features, JavaScript has created its unique place in the web and app development. Developers can use JS in various different situations and different platforms without any hassle.

There are over 50 JS frameworks available in the market, which makes difficult to come to a conclusion as to which JS framework is best for frontend.

But with the advent of popularity and usage of trending JS frameworks, here we have come out which JS framework is best for frontend development in 2021.

Most Popular JS Frameworks for Front end Development

 

1. React.js

React.js is an open source front end JS library created by Facebook in 2011 and became open source in 2013. React has come out as the one of the biggest influential frameworks in the web development domain that is delivering a breakthrough transforming web applications with advanced features.

React comes with a component-based, fully functional and declarative programming style for developing highly interactive user interfaces for primarily single-page web applications. React gives fast performance to boost apps with the use of its Virtual DOM because it renders only those components that have changed instead of rendering the entire page.

React uses simpler JSX syntax instead of JavaScript, making it simple to use and easy to learn. For its useful development features, React has become the most used JS framework for frontend development. World's big companies like PayPal, Netflix, Flipboard, WhatsApp, Airbnb

BBC are using React as their first choice for JS framework.

React is backed by Facebook and a large community of users and consistently being adopted by various industries. All of these makes React the top framework choice for 2021. However, as human is never perfect so its creation also would have some certain imperfections. Let's take a look at its various advantages and disadvantages.

Advantages of using React

Reusable components: React's component-based approach allows developers to import or reuse UI components.

Easy Integration: React provides easy integration with another front end and back-end framework such as PHP framework Laravel to work in tandem.

Simpler Syntax: React uses JSX JavaScript extension in the place of JavaScript that makes code easier to read and understand.

Virtual DOM: React gives a virtual representation (a copy of DOM called Virtual DOM or vDOM) to compare with the real DOM to only render components that have changed instead of rendering the entire page. This is the key to React's fast performance.

Disadvantages of using React: 

React is difficult to learn as compared to other frameworks like Vue.js.

React is often marked for poor documentation that cannot meet with new features.

React only works with the View Layer of the MVC Model giving limited options and to rely on other technologies to deal with Model and Controller Layers.

React is upgrading at a much faster pace which is causing difficulties for developers to be consistent with the learning cycle and maintain the knowledge with the updates.

2. Vue.js

If Angular.js and React.js ever had a child, it would like Vue.js. This framework has various similar features of Angular and React. Vue.js has been developed by Evan You- ex developer at Google.

Vue.js is an open source and lightweight front end JS framework used to build unique user interfaces and high-performance single page web applications with minimal efforts.

Vue has adopted most of its features from angular and react. One of the examples is that Vue gives a 2-way data binding as found in Virtual DOM in React and Angular.

This JS framework offers great flexibility features - developers can use it as an end-to-end full-fledged framework like Angular along with a view layer with state management similar to React.

Vue is simpler, dynamic, and progressive in functions that adapt to the developer's needs. World’s notable companies like Apple, BMW, Adobe, Nintendo and Louise Vuitton are using Vue.

Advantages of Using Vue

Simple: The structure of Vue is simple and allows developers to code more with type less syntax. Vue utilizes a single file component system which means that for any given component, CSS, HTML, and JavaScript all work in a single file.

Built-in MVC: It has an in-built MVC that allows faster configuration.

Easy to learn: Vue does not ask developers to learn JSX or TypeScript like in the case of React and Angular. It eases to grasp HTML templates that do not enhance the code complexity.

Documentation: Vue is blessed with the best documentation among all other JS frameworks. Any beginner developer with basic knowledge of JavaScript can manage documentation in a couple of hours.  

Disadvantages of using Vue.js

Small community of users: Unlike React and Angular which have large community of users, Vue does not enjoy the backup of a tech giant brand like Facebook and Google. On GitHub, Vue has 291 contributors which is far less than React's 1.6k contributors.

Limited employment opportunities: No doubt, Vue is on the rise due to its unique features. But Vue is still on its cradle stage, evolving. Vue is mostly used in the Asian market especially in Chine but in western countries like in the USA, Vue's popularity has not gained at a good extent.

Famous Websites Built with Vue

Apple Swift UI, BMW, Gitlab, Trivago, Upwork, Zoom.

3. Angular.js
