React uses JSX instead of regular JavaScript.
JSX is a JavaScript syntax extension that looks a lot like XML.
React JSX syntax
We don't necessarily need to use JSX, but it has the following advantages:
JSX executes faster because it is optimized after being compiled into JavaScript code.
It is type-safe and errors can be found during the compilation process.
Writing templates using JSX is simpler and faster.
