This article mainly introduces "what is the connection between react and javascript". In daily operation, I believe that many people have doubts about the connection between react and javascript. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what is the connection between react and javascript?" Next, please follow the editor to study!

React is a library encapsulated in the JavaScript language, a JAVASCRIPT library for building user interfaces that can be used to create Web user interfaces; it introduces a new way to deal with browser DOM, and gone are the days when you had to manually update DOM and laboriously record every state.

The operating environment of this tutorial: windows7 system, javascript1.8.5&&react16 version, Dell G3 computer.

React is a JavaScript library released by Facebook to build a user interface. React is mainly used to build UI, and many people think that React is the V (view) in MVC. React has high performance, the code logic is very simple, more and more people have begun to pay attention to and use it.

Because the design idea of React is extremely unique, it is revolutionary and innovative, and the performance is excellent, but the code logic is very simple. Therefore, more and more people begin to pay attention to and use it, thinking that it may be the mainstream tool for Web development in the future.

React is mainly used to build UI. You can pass many types of parameters in React, such as declaration code, to help you render UI, static HTML DOM elements, dynamic variables, or even interactive application components.

Advantages of using react

1. React is very fast.

It does not operate on DOM directly, but introduces a concept called virtual DOM, which is inserted between the javascript logic and the actual DOM with good performance.

Reactjs defines a set of dom model in the form of variables, all operations and conversion directly in the variables, which reduces the operation of the real dom, the performance is really quite high, and the mainstream MVC framework is essentially different, and does not deal with dom.

2. Cross-browser compatibility

Virtual DOM helps us solve cross-browser problems, providing us with a standardized API that is fine even in IE8.

3. Everything is component:

The code is more modular, it is easier to reuse the code, and the maintainability is high.

4. Unidirectional data flow

In fact, the core content of reactjs is data binding. The so-called data binding means that as long as some server-side data and front-end pages are bound, developers only focus on the implementation of the business.

5. Isomorphism, pure javascript

Because search engine crawlers rely on server responses rather than JavaScript execution, pre-rendering your application helps search engine optimization.

6. Good compatibility

For example, RequireJS is used to load and package, while Browserify and Webpack are suitable for building large applications. They make those difficult tasks less daunting.

At this point, the study on "what is the relationship between react and javascript" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
