If the drive is towards greater performance by leveraging native code, at what point do we just bypass the JavaScript runtime abstraction and build directly with a language like Rust?
The ecosystem seems to have hit a critical mass for web development. You now have incredibly mature and production-ready frameworks like Actix and Axum, along with innovative ones like Warp and Tide, providing everything you'd expect from routing and middleware to templating and native JSON handling.
There are crates for everything, like for databases, there's powerful options like sqlx for fully async compile-time checked queries or Diesel for a feature-rich ORM, so it feels like all the pieces are there.
I've written C for years. The only time it is safe from crashes is when the code doesn't churn and has consistent timing between threads. bun has constant feature churn and new hardware it runs on all the time providing novel timings. It is very unlikely going to be crash free any time soon.
