If no context is specified, all of the versions of the callback with different contexts will be removed.
(Mimics of the Underscore and j Query APIs, such as Lodash and Zepto, will also tend to work, with varying degrees of compatibility.) When working on a web application that involves a lot of Java Script, one of the first things you learn is to stop tying your data to the DOM.
It's all too easy to create Java Script applications that end up as tangled piles of j Query selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your Java Script logic, and the database on your server.
The callback will be invoked whenever the event is fired.
If you have a large number of different events on a page, the convention is to use colons to namespace them: Remove a previously-bound callback function from an object.
Simply create a new Collection with the When fetching raw JSON data from an API, a Collection will automatically populate itself with data formatted as an array, while a Model will automatically populate itself with data formatted as an object: However, it's fairly common to encounter APIs that return data in a different format than what Backbone expects.
For example, consider fetching a Collection from an API that returns the real data array wrapped in metadata: Each View manages the rendering and user interaction within its own DOM element.
If no event is specified, callbacks for all events will be removed. object.off("change", on Change); // Removes all "change" callbacks.
object.off("change"); // Removes the `on Change` callback for all events.

It could be as prosaic as a simple Underscore template, or as fancy as the React virtual DOM.
