This has been suggested by someone else but I'll suggest it again: Learn Rust. I was in your shoes a couple years ago, and decided I'm done with the Spaghetti. I got lured into Rust, somehow. It was the best thing that probably happened to my programming/development skills.

I've been doing some JavaScript (again) lately, and I have decided that I can only go on forward with TypeScript. Rust strict types, traits and patterns will completely change how you approach and think about code.
