Spot any places that you wrote a for-loop previously by intuition. Think again and see if it make sense to re-write it without using for-loop.

Further, its benefits are immediately obvious. If I refactor my application to use a binary tree for a collection instead of an array, I don’t have to rewrite all my loops!
map, on the other hand, will take some brain rewiring. I haven’t done any sort of functional programming since LISP in college and that has faded, and I daresay that I actually got the hang of LISP more than any of my classmates back then.

I’d suggest that the interest of your code being easily understandable to anyone who might need to see it would recommend using foreach until you have an application that significantly benefits from map, where map expesses something fundamentally different than a simple loop, rather than just expressing the same thing in an arguably better way.
