Defining point of functional programming

Question

I can enumerate many features of functional programming, but when my friend asked me Could you define functional programming for me? I couldn\'t.

Answer 1

I have to add that functional programming tends to also abstract control structures of your program as well as the domain - e.g., you no longer do a 'for loop' on some list of things, but you 'map' it with some function to produce the output.

i think functional programming is a state of mind as well as the definition given above.
