You can teach yourself the basics in 30 minutes by just mucking around with the tutorial and reference.
Typst is internally consistent and thus you can quickly go from zero, through basic syntax to knowing how to read the reference manual.
And this isn't some unusual flow either - the official docs guide you to do that. They start you with the tutorial, and then you just happen to land in the reference manual that lays out syntax, styling, programmability and then functionality.
