Just because functions are first class objects, there are closures, and higher order functions, does Javascript deserve to be called a Functional Programming language? The
I tend not to think of programming languages as having one particular paradigm, but that they lend themselves to certain paradigms. However just because they lend themselves to a particular paradigm doesn't mean you have to use that paradigm. It's quite possible to write object oriented programs in C and write imperative programs in ML. Not using a certain paradigm to solve a problem because the language isn't designed for it is just artificially limiting yourself (of course you should still take into account the limitations of a language when deciding if a particular solution will be a good solution).
