Knockout.js Lesson 5 - Observable arrays | Knockoutjs Video Tutorial

Today we're going to look at observable arrays in Knockout.js. Observable arrays are similar to observables, except that instead of subscribing to a single property and reacting when it's value changes, we can subscribe to an array and be notified whenever the array changes, either through having items added or removed, or through an operation like sorting or filtering. We use an observable array to store the photos that we receive from Flickr, and also work with jQuery's promise API.
