Objects Initializers
 --If we need one or two objects then Objects initializers is more useful than constructive function
  --But if we need hundreds or thousands of object then constuctive function or blueprint is more useful
26.	Adding methods to our objects
 --parenthesis is not used when we assign a method to the objects properties e.g
function people(name,age)
{ this.name = name; this.age = age; this.yearsUntilRetire = yearsLeft; }
this is our blueprint or constructive function and method is
 function yearsLeft()
{ var numYears = 65 - this.age; return numYears; }
 --Parenthesis must be used with the properties when we called a properties which is associated with a method
 e.g document.write(mainul.yearsUntilRetire());
Arrays
 --One name store multiple values
 --Array index is start from 0 or in broad sense we can computers counting start from 0
Define an array and accessed it values
Join and Pop
          --The join method is used to join all array elements in a string
          --We can also separate string element by usnig our customize separator like comma semicolon etc.
          --The pop method is used to remove last element from the array
