The return statement is used to specify the value that is returned from the function.
So, functions that are going to return a value must use the return statement.
Tutorial
The function below should return the product of two nos (a and b).
function prod(a, b)
{
x=a*b
return x
}
When u call the function above, you must pass along two parameteres:
product=prod (2, 3)
The return value from the prod() function is 6, and it will be stored in the variable called product.
