Key features and benefits

Among the main benefits of ReactJS are the use of a virtual DOM for efficient web page loading and server-side rendering, which does most of the page rendering on the server side and contributes to the high performance of the web application. A virtual DOM is a very efficient capability of ReactJS. It’s a tree based on JavaScript objects created with ReactJS that mimics the web page DOM tree. Every time we change something in the DOM, ReactJS employs a different algorithm that only refreshes and renders the changed DOM nodes. This contributes to the performance and loading of the DOM, which enhances the end user experience when visiting ReactJS-based websites on desktop and especially mobile devices.
