If I have a bug with how I’m using a library, I like to:

  • find a code example in the documentation
  • make sure it works
  • slowly change it to be more like my broken code
  • test if it’s still working after every single tiny change

Illustration showing a bunch of points with arrows between them. Each point has a check mark beside it, until one that is labelled “Oh THAT’S what broke it!!!”

This puts me back on solid ground: with every change I make that DOESN’T cause the bug to come back, I know that change wasn’t the problem.
