Bun, Forrest, BUN!!
summary
Bun is a drop‑in replacement for Node/npm that uses JavaScriptCore and is written in Zig with C/C++ bindings; it bundles a fast installer, bundler, transpiler, hot reload, and a test runner with TypeScript and Jest compatibility. Measured installs show bun install beating npm install by about 73.5% faster in the demo, but create‑app scaffolding can be slower. API coverage is roughly 70% full, 12% partial; 1.0 is stable but gaps and V8‑specific APIs remain.
