As a member of the Zig core team, one of the most impactful projects I’ve been involved with is the implementation of incremental compilation into the Zig compiler.
This feature allows the compiler to detect which individual functions and declarations have changed since a project was last built, recompile only that code, and directly patch the resulting bytes into the output binary, making the rebuild extremely fast.
The Zig project has been working towards this feature for a long time, and over the last few release cycles, it has finally gone from a proof-of-concept quality feature to one whic
