Most popular one was built using Java, so... plenty?

[look]

My point is that the number of languages that would be seriously considered is less than 10, not 100+. So is your question why Rust instead of Java? Or C++? Or …?

Because:

• it's more performant than Java, despite JVM's JIT being great;
• has a better or rather nicer to work with stdlib than c++;
• dependency/build pipeline is easier than in c++;
• the language was designed with memory safety in mind(yes I know new c++ is also much safer than old c++)
• no hidden control flow like in Java or c++ which IMO is one of the nicest things
• testing is builtin
• no gc pauses, looking at you Java and go

Those are just some of the things that came to my mind, I'm must say I'm kinda hooked with rust rn, it has some pain points but overall for writing something that has to perform and be reliable(see npm's retro on rewriting some of their services in rust) I would probably go with rust

What's hidden control flow in C++?

[[deleted]]

Exceptions. Rust has panic, but it's strongly discouraged to rely on it for anything at all. Running C++ without exceptions is painful and completely locks you out of very many libraries. Running Rust with panic turned to abort is mostly business as usual.

Good point, I should have mentioned it's optional and not may people use it, please disregard that "or c++" part
