Jda is a systems language built from scratch — zero C, zero Rust, zero Python. Bootstrapped from raw x86-64 assembly, self-hosted, compiles itself. Beats C on LZ77 by 6.6×, sudoku by 1.5×, regex by 1.9× — running via Rosetta 2 x86-64 on Apple Silicon. 43ms compile time (33× faster than Rust). No GC. Green threads + channels. Tensors, autograd, AVX-512/CUDA/ROCm. 117 stdlib packages. 388 tests passing. https://jdalang.org
