ReactJS uses a virtual DOM (Document Object Model) which is a lightweight representation of the actual DOM. The virtual DOM is a copy of the actual DOM and any changes made to it are first made in the virtual DOM. Once the changes have been made, the virtual DOM is compared to the actual DOM, and only the changes are made to the actual DOM. This process makes ReactJS extremely fast and efficient.
Another benefit of ReactJS is that it uses reusable components. A component is a small, independent block of code that can be reused throughout a website. This means that once a component has been created, it can be used in multiple parts of a website without having to write new code. This makes development faster, more efficient, and less error-prone.

Large Community and Support
ReactJS has a large community of developers who actively contribute to its development and offer support to other developers. This means that there are a lot of resources available for developers who are just starting out with ReactJS. There are also many open-source projects and libraries available that can be used to extend the functionality of ReactJS.
ReactJS can be used for cross-platform development. This means that the same codebase can be used to create web applications, mobile applications, and desktop applications. This saves developers time and effort as they do not have to write separate code for each platform.
