How to convert an integer into an array of digits

Question

I want to convert an integer, say 12345, to an array like [1,2,3,4,5].

I have tried the below code, but is there a better way to do this?

Answer 1

var n = 12345;
var arr = ('' + n).split('').map(function(digit)  {return +digit;});

The map function, though, is only supported by recent browsers.
