Create a namespace in JavaScript

Create a namespace in JavaScript
It is used for keep our common javascript function and used where ever needed...

Step 1 : Common JS
 

// create nested namespace functions (factorial and Gamma Function)
var EasyMath = {
  fact: function(num)
  {
    Math.round(num);
    if(num<0)
     return "Undefined";
    var fact=1;
    for(var i=num;i>1;i--)
      fact*=i;
    return fact;
  },
  gamma: function(num)
  {
    Math.round(num);
    if(num<1)
     return "Undefined";
    var gamma = EasyMath.fact(num-1);
    return gamma;
  }
}

Step 2 : Your Page JS

var factorial = EasyMath.fact(inputValue);
var gamma = EasyMath.gamma(inputValue);
alert(factorial +"<=!=>"+gamma);
