Brilliant. I love these. I really love how you start out with a very simple, even "wrong", example of how to do things. Then you build on top of it to lead into higher concepts. I accidentally learned how web pack and modules work here too! This is the best way for me to learn, start with a simple naive example that's maybe even the wrong way to do things, and evolve into something more elaborate. Thanks for doing these!
