traversing a Backbone Collection

I have just started integrating backbone.js in my application. I have a question about traversing each model in collection.

I basically want to get urls of each model in the collection and attach those urls to its corresponding model. I'm doing it this way right now, and I just want to know if there is any other way of doing it?

getItemsURLs: function(collection){

    var idsInCollection = [];

    collection.each(function(model) {
       idsInCollection.push(model.get('id'));
    });

    makeServiceCall({
        data: idsInCollection,
        success: function(data) {
            collection.each(function(model,i) {
                model.set({ url: data.urls[i]});
            });
        }
    }); 
}

Using pluck is more concise:

var idsInCollection = collection.pluck('id');

(As pointed out by asawyer, pluck is more concise than map or each.)
