nice idea, but i don't think it works fully correctly (doesn't handle nested deep i don't think?). try this input:
flatten_array([[[],[1,2]],[[[3]]]]); // should get: [1,2,3], instead: [[],1,2,[[3]]]
my version doesn't work with that input either. still trying to debug it.
i fixed it, i think.
@getify, mine is working for any level of nesting :)
.. did you copy only portion of the code?
sorry, must have missed something, seems to work. thanks! updating my snippet now accordingly.
