map() transforms a sequence using a function we specify, whereas compactMap() does the same but unwraps its optionals and discards any nil values.
Ex: converting an array of strings into integers works better with compactMap(), because creating an Int from a String is failable.

Agree
Sometimes the best solution is just to copy and paste, don't overcomplicate stuff in advance.
Ship first, improve it later.
It's way better to improve something that's in prod than justifying: "It's taking longer because I'm trying to ship the best solution possible".
