Comments is a coding technique everyone learns particularly early, which makes sense as newbies need the extra hand-holding. However, there's a weird phenomenon where code comments go from a good thing to a bad thing very rapidly in your career. This lesson will teach you:

  • How comments end up hurting rather than helping, especially at scale and with large codebases
  • What you should do instead of adding a bunch of code comments
  • The fundamental mentality around writing good, clean, readable code, which Alex breaks down with a concrete refactoring example
