Webassembly

Zig is a modern systems language built to replace C. It keeps manual memory management and zero hidden control flow: no garbage collector, no runtime, and one statically-linked binary that runs anywhere. Install Zig from ziglang.org/download , scaffold a project with zig init, and you’ll have a working CLI tool in about 50 lines using comptime, error unions, and first-class C interop. The killer feature: zig build-exe -target x86_64-linux-musl cross-compiles to any target from any host with zero toolchain setup.
