It doesn't achieve the same thing, though. Functionally, for the computer, it's the same. But code has two audiences: the computer and the coder who has to read and write it. And from my perspective, the human is more important than the computer. And JSX is more than a convenience at first glance. You read a lot more code than you write. If all of my code was written like this, it would add significant cognitive load, make the code more difficult to reason about and slow me down.
