Python is normally considered to have "classical inheritance", but as a practical matter for day-to-day programming Python inheritance works very similarly to how JS prototypes work (eg, having an inheritance chain and checking methods as you go up the chain until you find something that implements what you're looking for). I find that when people try to emphasise how different JS is from other languages, what they generally mean is how different it is from Java. :)
