The h Programming Language - Docs - Playground - FAQ A simple, fast, open-source, complete and safe language for developing modern software for the web h Outputs: h h compiles hundreds of characters of source per second. I didn't really test how fast it is, but when I was testing it the speed was fast enough that I didn't care to profile it. h is completely memory safe with no garbage collector or heap allocations. It does not allow memory leaks to happen, nor do any programs in h have the possibility to allocate memory. No null Completely deterministic behavior No mutable state No persistence All functions are pure functions No sandboxing required h generates WebAssembly , so every binary produced by the compiler is completely dependency free save a single system call: h.h . This allows for modern, future-proof code that will work on all platforms. h has a sim...
