Maps : display keys/values in 2D array

[pixelsearch]

Hello everybody
I'm a total newbie to Maps in AutoIt. Instead, I used a few times the similar Scripting.Dictionary object (which is damn fast) . Maybe the advantage of Maps could be that, if one day MS removes the Scripting.Dictionary object (I doubt it but who knows...) then we'll be happy that Maps exist in recent versions of AutoIt.

Anyway, I just started to learn Maps and needed to display at same time the Keys & their corresponding Values. So I scripted this simple reusable function which seems to do the job and is called by one line :

_ArrayDisplay(_Map2D($mMap), "Map Keys & Values")

Here is the functional example corresponding to the pic :

; AutoIt 3.3.16.1 (Map)

#include <Array.au3>

local $mMap[]
$mMap["Beethoven"] = "Bee"
$mMap["Berlioz"] = "Ber"
$mMap["Chopin"] = Null ; create a key "Chopin" without assigning it a value

_ArrayDisplay(_Map2D($mMap), "Map Keys & Values")

Func _Map2D(Const ByRef $mMap)
    Local $aMapKeys = MapKeys($mMap)
    Local $aMap2D[Ubound($aMapKeys)][2]

    Local $iRow = - 1
    For $vKey In $aMapKeys ; or a simple For... loop as commented out below
        $iRow += 1 ; 0+
        $aMap2D[$iRow][0] = $vKey
        $aMap2D[$iRow][1] = $mMap[$vKey]
    Next

;~  For $i = 0 To Ubound($aMapKeys) - 1
;~      $aMap2D[$i][0] = $aMapKeys[$i]
;~      $aMap2D[$i][1] = $mMap[$aMapKeys[$i]]
;~  Next

    Return $aMap2D
EndFunc

I just tested it on 10.000 pairs of key/values created by using the code below and the return from the function was immediate :

For $i = 0 To 9999
    $mMap[$i] = $i + 10
Next

If you guys got some improvements for the function, please share them here, thanks.
