I think with the "No integers" part that isn't entirely true JavaScript has typed arrays now. So you could get an array of ints that way. I'm not familiar with them and whether they behave in a similar way as an int in a typed language like Java or C++, but from my reading it seems the integer view behaves (output wise) in much the same way as other typed languages integers.
