Adding JavaScript methods to Number

[ #26655 ]
Dear Log,

Some aimless JavaScript fun. Try it:

var protonum = (1).constructor.prototype;

protonum.upTo = function upTo (n, closure) {
  var orig_i = this;
  if(this > n) return;
  for(var i = orig_i; i <= n; i++) {
    closure( i, orig_i, n);

protonum.chr = function chr() { // perlish
  return String.fromCharCode(this);
}; = function th() {    // as in
  return this.toString() + this.th_suf();

protonum.th_suf = function th_suf() {
  var n = Math.abs(this);
  if(n != Math.floor(n))
   return 'th'; // least-bad, I guess.

  n %= 100;
  if(n == 11 || n == 12 || n == 13) return 'th';
  n %=  10;
  if(n == 1) return 'st';
  if(n == 2) return 'nd';
  if(n == 3) return 'rd';
  return 'th';

( 100 ).upTo( 112, function(i){
  print( "The " + + " character is "
    + i.chr() + "\n"


The 100th character is d
The 101st character is e
The 102nd character is f
The 103rd character is g
The 104th character is h
The 105th character is i
The 106th character is j
The 107th character is k
The 108th character is l
The 109th character is m
The 110th character is n
The 111th character is o
The 112th character is p

  • Where have you been all my life? Right under my nose! Right here in this browser!

    Javascript... giver of pain and pleasure!

    • It’s actually kind of fun.

      The language itself is kind of neat. It has hashes, lists, and closures, so you can easily speak Javascript with a lisp. It sure isn’t Lisp or Perl, but it’s quite tolerable. I’d rather write Javascript than PHP…

      And implementations across browsers now have a modicum of consistency, so you don’t pull your hair out all the time.

  • ord? Don’t you mean chr?

    ord does the opposite (take a char, return the codepoint).

  • I'm a little wracked out right now, but don't you want to mod 10 after mod 100 isn't 11-13? 122, after all, should be 122nd, not 122th.
