React is a tool that we can use to build UI components. It is especially for creating single-page applications. It allows us to create reusable components. It is fast, easy and scalable. It has one-way data binding. It provides an in-memory data structure cache. By using, react we can create large applications that can change the data without reloading the page. The main thing in React is that applications usually have a single root node. Everything in React will be managed by React DOM.
