« An example of what dynamic workflows can unlock at scale is the recent rewrite of Bun. Jarred Sumner used dynamic workflows to port Bun from Zig to Rust with 99.8% of the existing test suite passing, roughly 750,000 lines of Rust, and eleven days from first commit to merge. »

Making WebAssembly a first-class language on the Web – Mozilla Hacks - the Web developer blog
This post is an expanded version of a presentation I gave at the recent WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The 1.0 version of WebAssembly was already a great fit for low-level languages like C and C++, and immediately enabled many new kinds of applications to efficiently target the web.
