Javascript Functions (contd..)

Well, functions are very interesting and can be used in various ways. Let’s understand another kind of functions in the next video.

The return statement in a function is optional. If a function does not return anything, it returns undefined by default.

A function can be declared without a name and its body can become the value of a variable. In short, a variable can store a function. Such functions are called anonymous functions because they do not have any name of their own. The syntax of such a function is:
 

var x = function(){
   // function code here
}

x();
