JSXReact, introduced a new syntax named JSX, it gives JS in the ability to write HTML tags, do not need to add quotation marks. JSX's syntax seems to be a template, but after compiling it, it turns into a JS syntax, just a syntactic sugar in the process of writing.JSX's parser will help us read this syntax and deal with it.The following is a simple example.const element = This is actually equivalent to the following code:const element = React.createEl

What is JSX? When you write a component in react, you usually use the JSX syntax, which looks like it's written directly in the JavaScript code, essentially a syntactic sugar, and every XML tag is converted into a pure JavaScript code by the JSX conversion tool, Of course you want to write directly using pure JavaScri

JSX is not a new development language, but a syntax proposed by Facebook: A syntactic sugar that allows you to directly write HTML tags in JavaScript code. Therefore, JSX is essentially a JavaScript language.

JSX is not a new development language, but a syntax scheme that Facebook proposes: a syntactic sugar that can write HTML tags directly in JavaScript code, so JSX is essentially a JavaScript language.

However, this method is very advantageous for our daily development and does not require a lot of compilation steps.To use JSX on Client-side, you need to do two things: 1) include client JSX transpilation script 2) use JSX to mark the scripts scriptIn earlier versions of React, the

application has three main components: scheduler, storage, and view (React component).Facebook's engineering manager, Tom Occhino, says that because of their "very large" code base and large organization, they need to "somehow make the code more predictable". This has been done through Flux and React. Flux is a system architecture that is used to propel data unidirectional flow in applications.

JSX, or Javscript XML, is a set of XML syntax defined within JS. Currently, the compiler uses Babel as the JSX. This is why the Babel was loaded in previous installments.Facebook introduced JSX to address the complexities of front-end code engineering and maintenance difficulties.

efficiency. Imagine, after one months, you look back at the code you write, whether or not you understand a variable, the meaning of an if judgment; a new colleague wants to add a little new feature or fix a bug, does he have enough confidence in his code not to introduce any side effects? As functionality increases, the code can easily become more complex, and these problems will become more and more serious, resulting in a hard-to-maintain code. And react
