One point towards using Array prototype functions (map, filter, reduce, etc.), is that they are often much more readable.

For loops are harder to skim.

Still, I don't understand the for loop hate. I have seen people argue against 'pointless optimizations', in the name of readability. And while yeah, arr.filter().map() is probably faster to comprehend, you're still iterating through the array twice. Pointless optimizations, not so much when the array is thousands of elements long.
