What is React.js?

React js is a fast, scalable, and simplest ever open-source JavaScript library. It was first created by a software engineer of Face book. The javascript library is used widespread for building single-page applications with interactive user interfaces. It proficiently handles the view layer for the web and mobile apps and works only on the interactive user interfaces.

React attracted a huge fan base over a few years as it allows easy creation of reusable UI components. It allows developers worldwide to create large web applications and change data, without actually reloading the page. Hence, making itself the fastest and simplest JavaScript library for the user interfaces in the application. React js. can be seamlessly used with a combination of other JavaScript libraries like Angular Js.

Why React?

React js has proved its worth over time. Developers are preferring to react js over other front end web applications because of its extraordinary modular features. It is a simple, easy to grasp, and a relatively new framework attracting web audiences. Many tech giants have switched or are planning to switch to React js for their web apps.

Here are a few reasons to opt for react js in 2021

1. Simplicity served with professionalism

Frontend technology must be such that it is reusable and scalable. React js is a simple technology that is easy to adapt or switch. It follows a component-based approach and has a project management lifecycle. It is simple, yet it helps build professional web and mobile apps. Netflix, Facebook, Instagram, etc are a few beautiful apps that have React js as a front-end framework. 

React comes with a special syntax called JSX that allows easy blending in with the HTML and Javascript and is much easier to use and implement.

2. Easy to comprehend

3. Native Approach

React native is the javascript supported mobile app building framework. It is reusable, scalable, and easily maintainable. It helps with extensive code reusability and comes with a rich mobile UI library. React native helps build cross-platform apps i.e IOS, Android, and Web applications seamlessly.

4. Data Binding with Flux controls

React js helps in Enhanced App performance with FLUX controls. Flux control is a one- way data binding application architecture technique. It extends the flow of data to components over one control point called the dispatcher. Further, it helps easy debugging of self-contained components within larger React js apps.

5. Performance and dependency
