Return () Statement
The Return () Statement
The return statement is an optional statement in javascript. This mainly used to return a value from the function.
This statement is beneficial when we want a result while making calculations.
Syntax
function functionName (parameter 1, parameter 2)
{
Block of code
return value;
}
Code:
<html>
<body>
<h2>The Return Statement</h2>
<script>
function Sum(x,y)
{
return x+y;
}
total = Sum(2,3);
document.write ("Addition of two number is "+total);
</script>
</body>
</html>
In the above example, we have defined a function named Sum() have two parameters x and y.
So, by calling a function if we except addition in return. We must use a return() statement.
Otherwise, it does not return any value, the result will be undefined.
