| 7. 7. 2. 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. |
