Very brief. I'm not sure what this adds over reading the language documentation (which itself is not great). As it's entirely organized by language features it doesn't really talk about any larger scale design decisions, which is where I think language proficiency is really found.
- Learning Zig by Karl Seguin: https://www.openmymind.net/learning_zig/
- https://zig.guide/
- Free project-based online book Introduction to Zig by Pedro Park: https://pedropark99.github.io/zig-book.
- Ziglings, almost working programs you need to fix: https://codeberg.org/ziglings/exercises
Currently, doing something with Zig as a target language would spend many more tokens and produce subpar results.
