A function is a piece or block of code that separate from main code and execute wherever needed .
The Most Java script function syntax shown below.
 
   function FUNCTION NAME ( )
    {

    // Your Codes

    }

-a function start with keyword function followed by FUNCTION NAME .
-There are mainly two way to give name to function.
 1. First is  function deceleration . which create a function with out use of variable assignment .
  eg:
    function function1( )
    {
     $("div1").hide();
     }

2. The second one is function expression .which use of variable assignment .
  eg :
var function1= function( )
 {
   $("div1").hide();
  }

anonymous function :

The other type of function called  "anonymous function" .
anonymous function is also called self executing  function .that doesnot  have a name and it execute immediately when they are found in code.
The other important thing is the variable declare inside these types of function  available only at the time of its execution .
eg:
    function( )
   {
   }
