Increment a string with letters?

Question

I need to increment a string from.. let\'s say aaa to zzz and write every incrementation in the console (is incrementation even a word?). It would go s

Answer 1

Treat the string like it's a base 36 number.

Convert it to decimal, add 1, convert back to base 36, and replace any zeroes with the letter 'a':

var str= 'aaa',
    s= str;

while(str!=='zzz') {
  str= ((parseInt(str, 36)+1).toString(36)).replace(/0/g,'a');
  s+= ' '+str;
}

document.body.innerHTML= s;
