I hope you enjoyed this chapter! While none of these features were "mission-critical" features for our application to work, these are the kinds of features that your users will request as your application grows.
Specifically, we learned how to install jQuery and use it to aid in the creation of some basic JavaScript and we used it to make the deletion of posts and pagination a bit cleaner. Next, we added Gravatar images to the profile and list of posts to make our profiles much more interesting to look at.
That's it! Our application is ready for prime time. In the next chapter, we're going to secure the final pieces of our application and deploy everything so that the world can see what you've built.
