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.createElement({ ‘h1‘, {className: ‘greeting‘}, ‘He
