Thanks! Totally agree - you need to understand some programming basics in order to understand the examples in the code section. Things like variables and for loops.
Nice catch! Just to be clear, it was that we were incrementing our exponent but not our counter, is that right? I pushed up a fix, but let me know if there were other issues.
Thank you so much!! We really wanted to try to make it live alongside the code examples in GitHub, but still feel almost e-book like. We definitely hacked around the GH Markdown a bit to achieve this. Thanks for noticing!
Ahhhh thank you for mentioning this! This was _really_ important to us, because it was hard for us to find real code examples that worked, and when we did, they were hard to parse.
It's also why we put it in GitHub, so it could live alongside the code examples :)
