In my case, Zig was super-simple to pickup, I've been using rust for few years so I was already in the systems programming (as a hobby), and I also had to read some C/C++ during that time, that probably helped me too.

Other than that, I was and I am, mostly a frontend developer with ECMAScript and TypeScript experience. I think Zig is very close to both, because Zig has anytype, so you can do duck-typing like you do in JS, and it has programmable type system, just like TS. Not to mention that reflection is basically your daily bread in JS/TS.

TLDR: If you have some systems programming experience and you've done a bit of TS, I'd definitely recommend you to give Zig a try. One weekend should be enough. I did that literally single-handed, as I was recovering after wrist surgery.
