JSX is an extension of JavaScript syntax, and if you observe the syntax or structure of JSX, you will find it similar to XML coding. With JSX, you can carry out preprocessor footsteps that add XML syntax to JavaScript. Though you can certainly use React without JSX, JSX makes React very clean and manageable. Similar to XML, JSX tags have tag names, attributes, and children, and in that, if an attribute value is enclosed in quotes, that value becomes a string. XML works with balanced opening and closing tags. JSX works similarly, and it also helps read and understand a huge amount of structures easier than JavaScript functions and objects.
