What is React Js

React Js is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies. React allows developers to create large web applications that can change data, without reloading the page. It is fast, scalable, and simple.

Why To Use React Js

There are several reasons why developers choose React Js for their projects. Some of the main reasons include:

• Virtual DOM: React utilizes a virtual DOM, which makes user interfaces fast by updating only the parts that have changed, rather than re-rendering the entire page.
• Component-Based: React allows developers to create reusable components, which can be combined to build complex user interfaces.
• Declarative: With React, developers can create interactive user interfaces using a simple and declarative syntax.
• SEO Friendly: React can be used for server-side rendering, which makes it easier for search engines to index the content of a website.
• Large Community: React has a large and active community of developers, which means there are plenty of resources available for learning and troubleshooting.

In conclusion, React Js is a powerful and popular choice for building interactive and dynamic user interfaces. Its component-based architecture and virtual DOM make it a great tool for creating fast and scalable web applications.
