That's a nice article on a topic that needed to be written up (forEach v map).
Very nice that you provided actual reasons for using one or the other. I notice that a lot of people just use map() because it is the newest and shiniest, but forEach() still has its place. 👍🏽
Thank you for the support :)
Just a quick note here:
forEach is mutable - means he operates with the same piece of memory, allocated for defined array, but giving some CPU resources for restructuring this piece after some changes in loop
map is immutable - means it just allocates new place in memory for your results, where RAM is giving storaging resources and CPU does much less
So there is always a choice if you need to calculate slower but to save some memory, or vice-versa
Great explanation!
