Deno (with Typescript of course) is my "smaller Rust". Whenever I don't need the performance and efficiency of Rust, I fall back to Deno. The development speed is much higher while the result is reasonable fast and safe.

- Typescript (compared to other main stream languages like Go or Java) comes pretty close to Rust regarding the type system, e.g. discriminated unions (https://mkosir.github.io/typescript-style-guide/#discriminat...) or null-checks as "the second best version of null safety". (The best is still the option type.)

- Deno has an exceptional core api and std lib. Performance is great. In my experience it's very stable (except some newer Node APIs). The tooling is great and now the move to JSR and Node compatibility widens the ecosystem while trying to make it safer. I wonder how the Deno team plans to push JSRs adoption.

- It's single threaded. Yes, I think it's a feature. Multithreading via Webworkers might not be as fast as sharing memory, but it's much safer. I even think it has an edge over Go, if you don't need the extra performance of Go. Go is generally faster, esp. for computations. Web stuff in Deno is fast enough as they use Hyper under the hood.

I really hope JSR adoption will grow.
