I wasn’t trying to go into typing as much as using structs or objects when working with known data attributes. Sorry that it was a bit misleading.
The original actually went into using trees, sets, heaps, tries, etc., but it felt way too… ranty. After writing all that out, I realized that most of those other cases come up really infrequently, and that my biggest gripe was about not using structs or other pre-defined key container types. I thought it would be better to keep things short and focused.
Maybe I should re-write and publish a data structures edition.
I’ve worked on dev tooling in a fairly large company. Especially for cyber security, do not get a Mac. A lot of the tools are just different enough on a Mac that they will make your life much harder.
