console.log(humanize_format(1));
console.log(humanize_format(8));
console.log(humanize_format(301));
console.log(humanize_format(402));

HTML Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Formats a number to a human-readable string </title>
</head>
<body>
</body>
</html>
JavaScript Code:
humanize_format = function humanize(num) {
if(typeof(num) == "undefined") return;
if(num % 100 >= 11 && num % 100 <= 13)
return num + "th";
switch(num % 10) {
case 1: return num + "st";
case 2: return num + "nd";
case 3: return num + "rd";
}
return num + "th";

JavaScript: Tips of the Day
var functionName = function() {} vs function functionName() {}
The difference is that functionOne is a function expression and so only defined when that line is reached, whereas functionTwo is a function declaration and is defined as soon as its surrounding function or script is executed (due to hoisting).
For example, a function expression:
// TypeError: functionOne is not a function functionOne(); var functionOne = function() { console.log("Hello!"); };
Historically, function declarations defined within blocks were handled inconsistently between browsers. Strict mode (introduced in ES5) resolved this by scoping function declarations to their enclosing block.
'use strict'; { // note this block! function functionThree() { console.log("Hello!"); } } functionThree(); // ReferenceError
