Alphabetically sorting a backbone collection using a key

Question

I have a collection that needs to be sorted by on a particular key ('display'), I know that backbone has a default comparator that is not defined by default, but I am at a loss of how to actually implement it

 var listCollection = new Backbone.Collection(rebuiltArray.map(function(text){
  return {
    attribute: text,
    displayNames: displayNames[text]
  };

 }));

Thanks in advance for your help

Try the following

 var ListCollection = Backbone.Collection.extend({
     comparator: 'displayNames'
 });

 var listCollection = new ListCollection(rebuiltArray.map(function(text){
    return {
        attribute: text,
        displayNames: displayNames[text]
    };
 }));
