Advantages of Using React 
Advantages of 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.

In addition, the components of React, i.e. React Helmet and React Router, helps react js development company to build SEO-friendly applications.

How Do React Components Aid in Web Application Development?

React components are of two types: 

• Functional Components
• Class Components

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