Thanks guys, I will look into underscore... I was hoping to not pull in another dependency, but it looks really good.
So I have the comparison working by using forEach to look for it... this could be faster for certain. Sander, I know what you mean... but the requirement is to have all items loaded so we can filter instantly, and mass add/remove quickly. I'm using paging on Angular to show my lists (20 at a time) and that basically has incredible performance. I originally had all the items visible... but the filtering is instant as if there were 100 items, and the paging is smooth as well. With this many items, paging is just there to fill the requirement, I suspect users will b-line right to the filter. Luke, _diff looks like what I need.
