As for textual resources:
The book by Moritz Lenz is quite good.
There’s also this polished three-hour introductory lecture.
Combine that with reading up on details in the reference and you’re in for a decent start.
For help with questions, best join #raku and #raku-beginner on irc.libera.chat (or the Discord channels that are bridged), they’re very welcoming.
I’ll also throw this in, “A Raku Manifesto” by Daniel Sockwell (Part 1, Part 2, Part 3). Especially Part 3 was really eye-opening for me with regard to the question of what kind of programming language is good for personal and libre software projects.
