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

The example below can work from a...a to z...z.

String.prototype.replaceAt = function(index, character) {
  return this.substr(0, index) + character + this.substr(index + character.length);
}

String.prototype.inc = function() {
  var stop = 'z';
  var start = 'a';
  var currentIndex = this.length - 1;
  var string = this.replaceAt(currentIndex, String.fromCharCode(this.charCodeAt(currentIndex) + 1));

  for (var i = string.length - 1; i > 0; i--) {
    if (string[i] == String.fromCharCode(stop.charCodeAt(0) + 1)) {
      string = string.replaceAt(i - 1, String.fromCharCode(string.charCodeAt(i - 1) + 1));
      string = string.replaceAt(i, String.fromCharCode(start.charCodeAt(0)));
    }
  }
  return string;
}

var string = "aaa";
var allStrings = string;
while(string != "zzz") {
  string = string.inc();
  allStrings += " " + string;
}
document.getElementById("current").innerHTML = allStrings;
