Well I would prefer default arguments instead.
function split(s:String, delim:String):Array
{
if (delim == undefined)
delim = " "; // default to space character
...
}
So you can pass one or two arguments to the split function. That's
method overloading. You can also type one of your arguments as Object
and then check the type inside the function using the instanceof
operator. That's more method overloading. :) But no true method
overloading as in Java or C++.
