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.

Here's the full context of the snippet you're questioning:

> 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.
