A system programming language which prioritizes optimality, safety, and A programming language which prioritizes optimality, robustness, and
readability. clarity.
Zig is a small, simple language, yet powerful. Zig fits into the same niche
as C, except does everything better.
Zig ships with a build system that obviates the need for a configure script
or a makefile. In fact, existing C and C++ projects may choose to depend on
Zig instead of e.g. cmake.

## Feature Highlights ## Feature Highlights
* Small, simple language. Focus on debugging your application rather than
debugging your knowledge of your programming language.
* Ships with a build system that obviates the need for a configure script
or a makefile. In fact, existing C and C++ projects may choose to depend on
Zig instead of e.g. cmake.
* A fresh take on error handling which makes writing correct code easier than
writing buggy code.
* Debug mode optimizes for fast compilation time and crashing with a stack trace
when undefined behavior *would* happen.
* Release mode produces heavily optimized code. What other projects call
"Link Time Optimization" Zig does automatically.
