What framework is react?

react is a JavaScript development framework launched by Facebook to build user interfaces, making it easy to create interactive UIs; react component logic is written in JavaScript instead of templates, so users can easily pass it through the application data and separates state from the DOM.

The operating environment of this tutorial: windows7 system, react18, Dell G3 computer.

React is a JavaScript library used to build user interfaces. It originated from Facebook's internal project. Because the company was not satisfied with all the JavaScript MVC frameworks on the market, it decided to write its own one to build Instagram. website. After making it, I found that this set of things is very useful, so it was open sourced in May 2013.

React is a declarative, efficient and flexible JavaScript library for building user interfaces. React allows you to combine short, independent code snippets into complex UI interfaces. These code snippets are called "components".

Because the design idea of ​​React is extremely unique, it is a revolutionary innovation, has outstanding performance, and the code logic is very simple. Therefore, more and more people are beginning to pay attention to and use it, thinking that it may be the mainstream tool for web development in the future.

React is an open source JavaScript library that provides views of data rendered into HTML. React views are typically rendered using components that contain other components specified in custom HTML tags. React provides programmers with a model in which child components cannot directly affect outer components, efficient updates to HTML documents when data changes, and clean separation between components in modern single-page applications.

React makes creating interactive UIs a breeze. Design concise views for every state in your app so React can efficiently update and render components correctly when data changes. Component logic is written in JavaScript rather than templates, so you can easily pass data around your app and keep state separate from the DOM.

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.
