A function can return a value using the return statement in conjunction with a value or object. return stops the execution of the function and sends the value back to the calling code. You can return more than one value from a function using return array(1,2,3,4). Following example takes two integer parameters and adds them together and then returns their sum to the calling program. Note that return keyword is used to return a value from a function.
