javascript - ReactJS - .JS vs .JSX

#short
#javascript
#html
#reactjs
#jsx

There are plenty of examples available on internet which use .js files with React but many others use .jsx files.
I have read about JSX files and my understanding is that they just let you write HTML tags within your JavaScript.
But the same thing can be written in JS files as well.
So what is the actual difference between .js and .jsx ?
