Iterating through an associative array in Flex

Always use an Object() type for an associative array. Do not use the Array() form of an associative array, as it has no inherent advantages, and doesn’t work well with iteration.

Moreover, if you are trying to iterate through an associative array of type Object(), remember the following:

Does it work? (YES):

for (var key:Object in myAssocArray) {

Alert.show(key + “ = “ + myAssocArray[key]);

}

Does it work? (NO):

for each (var key:Object in myAssocArray) {

Alert.show(key + “ = “ + myAssocArray[key]);

}
