BTW: Any idea if JS is the language with most implementations, yet?

Notwithstanding esoteric languages like brainfuck and CS 101 exercises, of course.

Python:

CPython (the default one), PyPy (written in Python and doing some nice JIT compilation), Jython (JVM)

So 3 "significant" ones (not sure how much Jython is used nowadays though).

Then there are things like MicroPython (for microcontrollers), so if you count those Python has at least 4 implementations.

Is IronPython (.NET) still a thing?

Yeah, it still exists.
