Error Messages In Tutorials
Getting hit with a typo error when you're trying to learn something else is a waste of time, energy, and motivation.
The Status line is there to prevent type errors, but we won't ignore error messages. Learning to read them is a critical part of learning a programming language.
Error messages can come from two categories of mistakes:
- Doing something wrong
- Typing something wrong
We'll look at both types, but we'll do it intentionally using Source Code blocks specificaly designed to demonstrate them.
The first thing is to point out that "wrong" in this context is not bad. It's more like when you walk up to a door and try to open it by pushing instead of pullling. You tried to do the wrong thing, but there's nothing bad about it. You do it another way until you find something that works.
