The react in the front-end framework refers to React.js, which is A JavaScript library launched by Facebook for building user interfaces. React is mainly used to build UI. Many people think of React as the V (view) in MVC. React has high performance and very simple code logic. More and more people have begun to pay attention to and use it.

React originated as an internal project at Facebook. Because the company was dissatisfied with all the JavaScript MVC frameworks on the market, it decided to write its own to build the Instagram website. After making it, I found that this set of things is very useful, so it was open sourced in May 2013.

ReactJS is a set of JavaScript web libraries built by Facebook and mainly used to build high-performance and responsive user interfaces. React solves a common problem faced by other JavaScript frameworks, which is the processing of large data sets. Being able to use a virtual DOM and use the patch installation mechanism to re-render only the dirty parts of the DOM when changes occur, React is able to achieve much faster performance than other frameworks.

Features of React

• Declarative design: React adopts a declarative paradigm, which makes it easy to describe applications.

• Efficient: React minimizes interaction with the DOM by simulating the DOM.

• Flexible: React plays well with known libraries or frameworks.

• JSX: JSX is an extension of JavaScript syntax. JSX is not required for React development, but it is recommended.

• Components: Building components through React makes it easier to reuse code and can be well applied in the development of large projects.

• One-way response data flow: React implements one-way response data flow, thereby reducing duplicate code, which is why it is simpler than traditional data binding.

Mastering React can not only help you deal with front-end application development, but its programming ideas can also be applied to back-end development of React Native native App development and server-side rendering. So whether you are engaged in front-end development or not, learning React will be of great help to improve your skills and career development.
