These two are the most straight-forward of all the Web Hacking rooms. They go over the basics of how changes in http code affect what you see on a computer screen and how some scripting in javascript makes pages dynamic. It's important to go over these sections as know what code you're injecting before you push the enter button is important. These rooms go bare minimum though, even after completing them I was still pretty lost when it comes to reading and creating malicious http and javascript code. Definitely read up more on web hacking past this room if you really want to understand how it works.

Burpsuite is a sweet tool to have for any web exploitation or even troubleshooting. In this room it breaks down how it works, what each section does, and how you will use it in future rooms. I think this room is the best out of the web hacking rooms and should be considered a go-to for anyone looking to start web hacking and protection.
