Isn't one of the main purposes of WebAssembly how it's like... portable/easy to run in different places? If you are in the backend, why not run a backend language like Rust in the first place + not introduce WebAssembly?

There are many other properties that WebAssembly gives us that would be hard (impossible?) to achieve with native Rust. Erlang-like fault tolerance based on a concurrency model where each unit gets their own heap. Fine-grained per request sandboxing. Green thread based async model. Hot reloading, ...

The sentence you extracted that quote from provides one answer to your question: it means they can take part of the backend code and actually execute it in the browser. Like edge functions, but even more so.

> One of the drawbacks of LiveView is that it requires a permanent connection to the backend, but because lunatic uses WebAssembly on the backend we can actually move part of the backend into the browser to allow for low-latency and offline use cases. Hopefully, you will be able to "just write" rust backend apps, but automatically get rich user experiences with offline support.
