In this video I take you through a way we can implement the Observer Pattern using Javascript.
The Observer Pattern works by defining a model and then a bunch of other dependencies (observers) on that model - so that when the model changes state, all the dependencies are notified of the change.
You will be developing a page with a button, when the button is pressed a number is incremented and a color is chosen at random - the number and color change are represented in the HTML page itself and the console.
This was inspired by java.util.Observer and java.util.Observable.
