Basic Example

arrayEach(
    aNames,
    function(element) {
        dump(element);
    }
);

Parallel Example with 3 Threads
start = getTickCount();
a = ["a","b","c","d","e","f","g","h","i"];
arrayEach(
    a,
    function(element, index, array) {
        writeOutput("<code>#index#:#element# [#getTickCount()#]</code><br>");
        sleep(100);
    },
    true,
    3
);

writeOutput('Total Time: #(getTickCount()-start)# milliseconds<br>');
