I’ve only been coding with Python/Javascript since I started my career. I do APIs and websites frontend. I don’t really understand what is interesting in learning an other language. For example, I could learn Ruby, but I’d do the same thing I already do.
Rust, C/C++ tho seem to me to be languages to code other things. Hence my question : what do you code? If possible, make distinction between personal projects and professional projects.
I use Rust mostly because I am comfortable working with it. It hits a sweet spot of often letting me write in a functional style, at often zero or very low cost. It has a lot of high quality libraries, for almost any purpose. And the language itself comes with great things too. Traits, Option, and Result are all things I miss when working in other languages like Go.
It’s also a memory safe language that is also fast, approachable, and has a ton of good documentation. What’s not to like?
