I wish I could upvote this multiple times. map is very cool, and can give you a marvelously compact syntax, but a simple foreach or while loop does the same thing and is (usually) easier to read.

    I use map, not for its "compact syntax", but depending on the use case. This example, in my opinion, is the perfect use case for map: transform an array using some criteria and return a new array.

    for (or, foreach if you like) has its place, but I don't find it inherently more readable than map.
