Zig is a general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software. Robust: Behavior is correct even for edge cases such as out of memory. Optimal: Write programs the best way they can behave and perform. Reusable: The same code works in many environments which have different constraints. Maintainable: Precisely communicate intent to the compiler and other programmers. The language imposes a low overhead to reading code and is resilient to changing requirements and environments.
