The length property does not apply to associative arrays, also known as “Named arrays.” An associative array is really just a generic object with properties. To get the number of items in an associative array, you can use a for…in loop and a counter:

Dus:
var test:Array = new Array();
test[0] = "foo";
test[1] = "bar";
trace(test.length);

zal als output 2 geven. MAAR!

var test:Array = new Array();
test['a'] = "foo";
test['b'] = "bar";
trace(test.length);

geeft als output 0. Wtf? Nen uitleg da ik hier vond:
