I'm not sure if it really makes a difference in this case (I've never 
bothered to check), but here's an article written by Kris Coppieters 
which explains the idea behind it...

FWIW, I use this function to get an array when I deal with a large 
number of objects and I don't specifically need a dynamic collection 
over an array. I don't need to worry about whether I'm starting out with 
an array or a collection and the difference in performance is tremendous:

function AsArray(collection){
    if(collection instanceof Array){return collection.slice(0)}
    return collection.everyItem().getElements().slice(0);
    }
