Sorting Backbone collection alphabetically

Is there a way to do this out of the box with the _.sortBy method or any other part of the library?

Since you tagged your question with the backbone.js tag, I'm assuming you mean to sort a collection, you just need to provide a comparator function on your collection and backbone will keep the collection sorted.

If your question is specifically alphabeticical sorting, I believe that is the default sort, from the backbone.js documentation (I linked to it above)

chapters.comparator = function(chapter) {
  return chapter.get("page");
};

You mean like this?

var array = [
    { name: "banana" },
    { name: "carrot" },
    { name: "apple" }
];

var sorted = _(array).sortBy("name");

I'd say it works out of the box.

If you wanted to sort an ordinary array of strings, you probably just want to use sort:

var flatArray = ["banana", "carrot", "apple"];

flatArray.sort();

See here. Also works.

Note that Underscore's sortBy returns a new array which is sorted, where JavaScript's built-in sort function sorts an array in place.
