The tl;dr series is meant to be a quick summary of a topic with just enough information to get you from knowing nothing to being able to understand and work with the topic. All topics have a source-code file hosted on github.

**I have since got rid of this series — please do not hesitate to reach out to me if you do have any questions on the topics below. More than happy to help if I can :)

Note: these tl;dr’s used to be called “my notes”, literally. I am a self-taught developer and these are my notes. If they help you then perfect if you see a mistake even better (&
