It doesn't output what I expect :/

Question

What can I do to output this?
aaa
aab
aac
aba
abb
...
ccc

I've tried using a switch statement, but it just gives me:
aaa
And then stops.

Looks ok to me, you just need to print the char this might help

alert(String.fromCharCode(firstLetter+96) + "" +
String.fromCharCode(secondLetter+96) + "" +
String.fromCharCode(thirdLetter+96));
