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.
> In the same vein, you have `pow(1+1, 2) == 4` but `1+1 ** 2 == 2`, because the latter is interpreted as `1+(1 ** 2)`. 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.
