Question

I noticed that i can set a return type on a function to ‘Void’ aswell as ‘void’ and just wondered if there was and benefit of either?

Answer 1

Void (with uppercase “v”) was ActionScript 2 version of ActionScript 3 void.

AS3 docs (void):

Specifies that a function cannot return any value. The void type is a special type that contains exactly one value: undefined. It is special in that its use is limited to the return type of a function. You cannot use void as a type annotation for a property.

AS2 docs (Void):

The Void data type has one value, void, and is used in a function definition to indicate that the function does not return a value, as shown in the following example:

//Creates a function with a return type Void
function displayFromURL(url:String):Void {}
