Performance: React.js use JSX, which is faster compared to normal JavaScript and HTML.You can see a UI broken down into multiple individual pieces called components and work on them independently and merge them all in a parent component which will be your final UI. Components make the task of building UIs much easier.

In other words, we can say that every application you will develop in React will be made up of pieces called components. Component: A Component is one of the core building blocks of React.One-way Data Binding: This feature gives you better control over your application.Manipulating DOM is slow, but manipulating Virtual DOM is fast as nothing gets drawn on the screen. It is exactly the same, but it does not have the power to directly change the layout of the document. So for every object that exists in the original DOM, there is an object for that in React Virtual DOM. Virtual DOM: Virtual DOM exists which is like a lightweight copy of the actual DOM.It makes it easier for us to create templates. Use JSX: It is faster than normal JavaScript as it performs optimizations while translating to regular JavaScript.The declarative view makes your code more predictable and easier to debug.įeatures of React.js: There are unique features are available on React because that it is widely popular. It designs simple views for each state in your application, and React will efficiently update and render just the right component when your data changes. React uses a declarative paradigm that makes it easier to reason about your application and aims to be both efficient and flexible. It is an MVC architecture-based library that plays the role of “C” which means control. React.js is an open-source, component-based front-end library responsible only for the view layer of the application. Reasons to learn React: React is a declarative, efficient, and flexible JavaScript library for building user interfaces.
