Edit: This is a quantitative question. I want to know which has more of something. It is a matter of one has 4 and the other has 8. Nowhere in the question does anyone's opinion play a part.

Python and Javascript both have features that allow them to be used in a functional way e.g. Lambda, map(), filter(), and reduce(). The problem is, I'm new to functional programming, and don't know all the other functional stuff that may be provided by these languages. So, which of the two provides more functional programming features that facilitate functional-style programming?
