JSX is 99% map/filter and boolean expressions. It's written between curly braces to be evaluated as a JavaScript expression. I don't understand how it's different from regular JavaScript.

It uses tag syntax, which regular JavaScript doesn’t at all. Browsers cannot parse it. These are meaningful differences.

None of that matters to a React developer. If you know JavaScript, you know JSX.

I don't understand how that is relevant to the quote I was replying to: "React is great because it's vanilla Javascript". Vanilla Javascript works in a browser with zero transpiling. That's important.

(also, "if you know JavaScript you know JSX" is objectively untrue! There are plenty of JS developers that don't work with JSX)
