Edit Question
Title
Body
PHP, for all its warts, is pretty good on this count. There's no difference between an array and a hash (maybe I'm naive, but this seems obviously right to me), and to iterate through either you just do foreach (array/hash as $key => $value) In Ruby there are a bunch of ways to do this sort of thing: array.length.times do |i| end array.each array.each_index for i in array Hashes make more sense, since I just always use hash.each do |key, value| Why can't I do this for arrays? If I want to remember just one method, I guess I can use each_index (since it makes both the index and value available), but it's annoying to have to do array[index] instead of just value . Oh right, I forgot about array.each_with_index . However, this one sucks because it goes |value, key| and hash.each goes |key, value| ! Is this not insane?
