With no context, this could be an honest attempt to learn about different tools, a thinly veiled set-up to promote a specific language, or an attempt to stir up drama. I can't tell which.
It's curious how such specific conditions are embedded into the question with no explanation of why, yet "memory safe" is included among them without specifying what kind of memory safety.
Rust
Ada, hands down. Every time I go to learn Rust I'm disappointed by the lack of safety. I get that it's miles ahead of C++, but that's not much. I get that it strikes a much better balance than Ada (it's not too hard to get it to compile) but it still leaves a lot to be desired in terms of safe interfacing. Plus it's memory model is more complicated than it needs to be (though Ada's secondary stack takes some getting used to).
I wonder if any other Ada devs have experience with rust and can make a better comparison?
Hands down, Rust 🦀
Rust.
I started learning Go about 3 months ago and it quickly became one of my favorite languages. It feels like C with a bunch of Python niceties thrown in. And performance isn't super critical in my work so being garbage collected is fine with me.
People don't understand that JIT languages are still compiled, JIT literally describes when it's compiled.
That said, F# and/or OCaml.
Swift
Rust and Haskell (I think Haskell counts)
Scala 3 native. If the compiler was faster I'd be even happier. Curious to try Ada
Nim
Nim. Small compiler, small executables, easy to understand (except the macros, I still can't get my head around them).
FreePascal. Yeah yeah, Pascal's dead, etc etc, but it being so verbose and strict certainly help programmers (or at least me) keeping things somewhat tidy.
Also shoutout to V
After months of no practice, I forget quite a lot of stuff about them, regardless of language; therefore, none
EDIT: None of them is memory safe, that is
Crystal, but only because I’m a full time Ruby on Rails (and sometimes Hanami!) programmer.
It’s fantastic, and I had an excuse to use it at work when we needed to gather PHP Watchdog logs from a MySQL database and format, output them to STDOUT in a Kubernetes environment. (This was necessary for our log monitoring tools expecting data in a standard way, AKA not connecting to a database. 🤦♂️)
I know there are perhaps better options out there (Go, Rust, etc.) but from a Rubyist’s point of view Crystal gives you that “flow” from working in a beautiful language but with the performance boost of compiled software.
You mean... except Ada?
Kotlin is nice
You forgot that beauty - "undefined behavior"!
Memory-safety can guarantee only so much safety! C++ can still blow up in your face, even with all the alleged memory-safety built into C++, thanks to all the UB traps in C and C++.
Rust is the closest language that has no such "gotchas".
Java
Scala is the the first I used and I like it a lot. If I had more time I'd love to give ocaml a decent try but I don't think I can get into it these days.
D
C on Morello (or any other capability machine).
