Bun Switches from Zig to Rust: Why a High-Performance JS Runtime Changes Its Language(twitter.com)
Writing language: KoreanRead in the original language
Plain summary
- Bun creator Jarred Sumner announced that the version rewritten in Rust passed 99.8% of the existing tests.
- Zig was initially chosen because it made handling JavaScriptCore easier, but the lack of a package registry and fewer developers available to recruit eventually became a bottleneck.
- This is an example showing that choosing an unfamiliar language based solely on initial performance can lead to the cost of rewriting everything as the team grows.
