I should probably add this kind of thing to the article then. It is nearly impossible to state "Language X is compiled/interpreted/jitted".
I didn't explicitly say that JS doesn't come with JIT, because I'd be putting Node.JS and every browser engine in the same bag. I simply can't be sure about all of them.
I'll add very soon this caveat that the dialect (js, php, python) doesn't really matter and make it clear that I'm talking about engines, possibly directly point to them.
I hope you understand, though, that I wanted to make JIT as a concept understandable. The language comparisons are secondary.

Thanks a lot for your feedback!
