In JavaScript each object has a reference to its constructor (a function that was used to create the object). It's accessible as obj.constructor.

If you have a Backbone.js model, which is extended from Backbone.Model in this way: var YourModel = Backbone.Model.extend({});, you could create an object using new: var yourModel = new YourModel();.

Then, you could use yourModel.constructor:

yourModel.constructor === YourModel // true

Or instanceof:

yourModel instanceof YourModel // true
yourModel instanceof Backbone.Model // true
