We’re seeing two ways so far: the first is WebAssembly. Our tooling does not assume that you’re re-writing everything in wasm, but that you’re using it alongside JS, so you can use it only where it makes sense, and it’s easy to do so.

Second, in services. Microservice architecture means you can write parts of your applications in different languages, and we have really nice JSON handling, or whatever other format you’re using. People have moved high load services to rust and seen big gains.

Of course, there’s still lots of work to do, and there’s always compelling reasons to use other technologies too.
