Void or void is used when the method doesn't return a value.
function foo ():String
{
return someString;
}
so that method returns a string :)
I have seen people use void within a method that takes no arguments, like
this (but I would never do it):
function foo( Void):Void
{
...
video is prob Object - NOT a string.
