Return
When a function is invoked, it begins execution with the first statement, and ends
when it hits the } that closes the function body.
That causes the function to return control to the part of the program that invoked
the function.
The return statement can be used to cause the
function to return early. When return is
executed, the function returns immediately without executing the remaining
statements.
A function always returns a value. If the return value is not specified, then undefined is returned.
If the function was invoked with the new prefix
and the return value is not an object, then
this (the new object) is returned
instead.
