TypeScript tip: If you don't know the type of something, use `unknown` instead of `any` any basically means I don't care about this type, just let me do anything on it. That's bad unknown, however, means I don't know this type and I'm not really using it. That's much better

REST is great for resources that are independent of each other. When you introduce relationships, things become a graph. Querying a graph with a REST API is like eating a salad one vegetable at a time.

“but will this edge case really ever happen?” YES. And when it does it’ll make your users not trust your app.

Command line tip: The $_ bash command variable holds the most recent used parameter. For example, you can: mkdir ~/some/path Then: cd $_ to get into that new directory.

Coding Tip: When you need to take a long break, or at the end of the day, leave your code in a problem state (red test, error on screen, ...) This makes it easier for you to resume and remember exactly where you left things off.
