Returning Values

JavaScript provides a return statement to return a value.

The value to be returned is placed after the keyword return.

The "undefined" value is returned from a function if no value is specified after the keyword return or if the return statement is not used.

A value returned from a function can be assigned to a variable or used within an expression.
