allKeys_.allKeys(object) Retrieve all the names of object's own and inherited properties. function Stooge(name) { this.name = name; } Stooge.prototype.silly = true; _.allKeys(new Stooge("Moe")); => ["name", "silly"]

every_.every(list, [predicate], [context]) Alias: all Returns true if all of the values in the list pass the predicate truth test. Short-circuits and stops traversing the list if a false element is found. _.every([2, 4, 5], function(num) { return num % 2 == 0; }); => false

after_.after(count, function) Creates a version of the function that will only be run after first being called count times. Useful for grouping asynchronous responses, where you want to be sure that all the async calls have finished, before proceeding. var renderNotes = _.after(notes.length, render); _.each(notes, function(note) { note.asyncSave({success: renderNotes}); }); // renderNotes is run once, after all notes have saved.
