Actually, that’s not a bad exercise: you should try to add updating user info to this page and see if you can get it working. You’ll need to edit /views/index.jade, /routes/users.js, /app.js, and /public/javascripts/global.js just like for adding and deleting.

In the GitHub repo below is this last exercise completed. Of course it is best to figure out how to do this on your own but if you get stuck, this is how I did it. So this is the last step of Christopher Buecheler’s outstanding tutorial. Here I complete the lesson with the last part of the CRUD operation with the UPDATE step. While this tutorial does not program in a very modular, best practices way, it does explain the basics really well.
Ok. Now back to all the legacy stuff and debugging IE8.
