There are so many open-source platforms for making the front-end web application development easier, like Angular. ReactJS is very very simpler to build a professional website and mobile applications. ReactJS is very easy to learn. Anyone with a basic previous knowledge in programming can easily understand ReactJS. One of the most important use of ReactJS is reusability. That means it will support the code reusability extensively. So at the same time we can make IOS, Android and Web application.
Virtual DOM is one of the best feature of Reactjs. React creates its own virtual DOM where your components actually live. This approach gives you gains in performance because React calculates what changes need to be made in the DOM beforehand and updates the DOM tree accordingly. Browsers are slow and the DOM API is hard to deal with. You can see Virtual DOM as a fake browser that is much faster. React’s fake browser acts like an agent between you and the real browser.
