Convert integer into its character equivalent in Javascript

I want to convert an integer into its character equivalent based on the alphabet. For example:

0 => a
1 => b
2 => c
3 => d

etc. I could build an array and just look it up when I need it but I'm wondering if there's a built in function to do this for me? All the examples i've found via Google are working with ASCII values and not a characters position in the alphabet.

Cheers. :)

Assuming you want lower case letters:

var chr = String.fromCharCode(97 + n); // where n is 0, 1, 2 ...

97 is the ASCII code for lower case 'a'. If you want uppercase letters, replace 97 with 65 (uppercase 'A'). Note that if n > 25, you will get out of the range of letters.
