Zig

Zig is a modern systems programming language and toolchain: it delivers C-level performance, zero-dependency cross-compilation, and powerful compile-time metaprogramming via its `comptime` feature.

Zig is a general-purpose, statically typed systems language designed by Andrew Kelley to improve upon C: it prioritizes robustness, optimality, and reusability. The toolchain acts as a zero-dependency C/C++ compiler, providing seamless cross-compilation for dozens of targets right out of the box. Its core differentiator is `comptime` (compile-time code execution), which handles generics, reflection, and metaprogramming without a preprocessor. For memory, Zig uses manual management with explicit allocators, eliminating hidden control flow or memory allocations. Companies like Uber and TigerBeetle leverage Zig for high-performance, low-level software.
