So now just lets complete the third task, i. Emits events when data changes. But one of the important aspects for Web development is to provide a Rich user interface with UX user experience. The Backbone object itself mixes in Events, and can be used to emit any global events that your application needs. According to the docs: Please do not update changed directly since its state is internally maintained by set.
