Zig’s Incremental Compilation Cuts Rebuilds to Sub‑100 ms
The Zig compiler now supports incremental compilation, detecting changed functions and declarations and recompiling only those, patching the binary directly. In practice, a 5‑second full build drops to 50‑70 ms for subsequent changes, speeding iteration for complex apps. This moves Zig from proof‑of‑concept to production‑ready.
