We have defined the essentials of a video player and now need to abstract it a bit further so it can be reused and managed much better. Following some conventions and creating a flexible framework will help us move faster and more effectively.

First, let's think about some things we may want from this class:

  • An events method that attaches the proper events

  • Callback methods that can be defined, for example, onPlay, onPause, and onEnded

  • Public methods that can be called from outside the instance

  • Chainable methods similar to jQuery where you can call one method after another, for example, fadeIn().fadeOut().show().hide()

Having a list of items that abstract the behavior of a class is a step in the right direction for establishing a solid framework or library. Now let's start by creating callbacks...
