Discovering the HTML5 History popstate event

In the last few videoa we toke a break from the History API to learn how to work with the XMLHttpRequest. Once we created a page that loads in content dynamically without refreshing the page we used the pushState to update the URL of the page. The next step in this process is to be able to change the content on our page as the user clicks on the back/foreword in there browser to accomplish that we will need to work with the popstate event.
