private function arrayMapper(item:uint, index:uint, array:Array):uint {
return item + 30;
}
trace([1, 2, 3, 4, 5].map(arrayMapper));
// traces 31,32,33,34,35
Array.map() does what it says it does.
private function vectorMapper(item:uint, index:uint,
vector:Vector.<uint>):uint {
return item + 30;
}
trace(new <uint>[1, 2, 3, 4, 5].map(vectorMapper));
// traces undefined
Vector.map() does, well, f-all. I can use forEach() to get what I want
but this doesn't look right.
Thanks for testing MM!

You're right Kenneth.
var g:Vector.<uint> = Vector.<uint>([1,2,3,4,5]);
var hh:Vector.<uint> = g.slice();
var h:Vector.<uint> = g.map(mapper);
var a = 5;
function mapper(item:uint,ind:uint,g:Vector.<uint>):Vector.<uint>{
trace(g[ind]+30);
return g;
}
In this case, hh returns the vector, and h still returns null.

What do you get for h?

Hi Kenneth...
This is working for me:
var g:Vector.<uint> = Vector.<uint>([1,2,3,4,5]);
var h:Vector.<uint> = g.map(mapper);
function mapper(item:uint,ind:uint,g:Vector.<uint>):void{
trace(g[ind]+30);
}
Hope that helps,

Dear coders,
Vector.map() is supposed to return a new Vector but it appears to return
nothing (undefined). Is this working for you?
