This article mainly explains "is react a kind of JavaScript language", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "is react a kind of JavaScript language?"

React is not JavaScript, but a library written in the JavaScript language, a declarative, efficient, and flexible JS library for building user interfaces; using react, you can combine short, independent code snippets into a complex front-end UI interface.

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

JavaScript is a high-level, interpretive programming language; it is a prototype-based, function-first language, and a multi-paradigm language that supports object-oriented programming, imperative programming, and functional programming.

React is a declarative, efficient and flexible JavaScript library for building user interfaces. Using React, you can combine short, independent code snippets called "components" into a complex UI interface.

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.

The project itself is getting bigger and bigger, from the earliest UI engine to a complete set of front and back Web App solutions. Derivative React Native project, the goal is even more ambitious, hope to write Web App to write Native App. If that happens, the entire Internet industry will be upended because the same group of people only need to write UI once to run on servers, browsers and mobile phones at the same time.

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.

For enterprises, react is the dividing line between junior Web front-end engineers and middle and senior front-end engineers. With the innovation of Internet technology and the influx of more and more people into the front-end industry, the threshold of enterprise recruitment is raised, and react can be seen as the first network for handsome talent selection.

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, I believe you have a deeper understanding of "is react a kind of JavaScript language?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
