If -2 ** 2 returned me -4 in JS I would be confused.
JS is not a math language, it's a programming language. We have basic math
operations on its syntax and that's fine.

Where is this going to? Am I supposed to read the `1+1 ** 2 == 2` is a
sugar for `pow(1+1, 2)`? that's not my reading.

Python does not follow a standard implemented in many different
implementations governed by different ppl and orgs. Any behaviour, even the
unexpected, becomes a feature, it's an easy field and canvas. I'm glad JS
aims for a consistent and unambiguous path, even if that can't make
everyone loving the syntax.
