Why doesn't babel compile React code (error: unexpected token)?

Question

JavaScript

I start babel, I try to compile the input file, I write an error in the console that it does not recognize the JSX object:

At the same time, the error appeared out of nowhere, I did not change the config, everything worked fine.

Answer 1

const jsx = uh, what, is that a curly brace?
No, it came from your ignorance and laziness. You should read at least something about jsx before you start writing code, so as not to embarrass yourself like this. Change brackets to round ones.

Answer 2

Why babel

Although I have not yet met people who babel jsx transpile
Usually this is used
