What Hacker News says
2 sourcesQuickJS is a simple interpreter, no JIT, so performance obviously won't be competitive with V8.
The appeal is that it supports most of ES2019 while being a easy to build, light weight dependency that can be embedded into Rust applications. [1]
Would I use something like this for a production service with a high traffic volume? It would be nice to see benchmarks, but most likely not.
But if you have a Rust backend and want a simple way to do SSR without having to operate a separate Node service or linking v8, this might be a neat approach.
ps: It would be nice to run QuickJS in a WASM runtime, while still offering the same convenient API surface for Rust. This would provide sandboxing for the QuickJS C code. It's is in my backlog, I might get to it eventually. [2]
