React is an open-source JavaScript library that is useful in building web application interfaces. React or rather ReactJS helps in building a stronger framework for its products by reusing components. There are two-parts in ReactJS – HTML code and HTML document. The user view layer or the User Interface (UI) is built using HTML code. The HTML page contains all of the components.

Some of the major companies that have used React include Whatsapp and Instagram. Thus, React was released to the public in 2013.

Advantages of Using React

Simple:
React is considerably simpler to understand and apply. Therefore, any developer with JavaScript experience can quickly grasp React and begin building web apps.

Reusable Elements:
One of the essential advantages of React is code reusability. Reusability simplifies the workload of developers. For similar app components, programmers do not need to create different scripts. Hence, they can reuse the code. Thus, code reusability helps to reduce production costs.

Easy Code Testing:
Another vital feature of React is testing. It contains native tools which help in easy testing and debugging. ReactJS component-based architecture reduces the need for extensive debugging. When you change one component of the app, it does not affect the others. As a result, React saves a lot of time for testing and troubleshooting.

SEO Friendly:
ReactJS allows for quicker web page generation. The page loading time for React applications is much lower than the others. Hence, the bounce rate of React pages is low. In addition, the components of React, i.e. React Helmet and React Router, helps to build SEO-friendly applications.

How Do React Components Aid in Web Application Development?

A React component is one of the core elements of React application. In other words, any application you create in React will be built using elements known as React components. Top reactjs development company developer can build the UI faster using React components.

React components are of two types:

1. Functional Components
2. Class Components

In addition to these two components, React contains other similar elements that aid in developing the application.
