Which Programming Language Is Best for Claude Code? - DEV Community

Which programming language is best suited for AI coding agents? "Static typing prevents AI hallucination bugs!" "No, skipping type annotations saves tokens!" There's plenty of qualitative debate, but quantitative data is scarce. So I ran an experiment. Experiment I asked Claude Code to implement a "mini-git" — a simplified version of Git — in various languages, and measured the time and cost for each. Git was famously built by Linus in two weeks, so it seemed like a good task. The task was split into two phases: v1 (New project): Implement init, add, commit, and log. v2 (Feature extension): Add status, diff, checkout, and reset. The prompt was simply: "Read SPEC-v1.txt, implement it, and make sure test-v1.sh passes." v2 was analogous.
