ABSTRACT
WebAssembly has been around for several years now, and we've all seen "hello world" demos.
But what's it like to deploy a large complex WebAssembly project into production for real users?
Brian talks us through how he built an online developer tool for a new programming language called Roc, putting a complex compiler into a web page.
Find out how WebAssembly affected the codebase, why he decided to use WebAssembly to generate more WebAssembly, and how he glued it all together with JavaScript. [...]

I like that Roc gets recognition it deserves

[@rez188]

Gleam also has a wasm compiler embedded in its tutorial. Its also written in rust but the code you write gets compiled to js instead of wasm

Great presentation!!!
