Which Programming Language Is Best for Claude Code?

Claude Opus runs 1.4–2.6× slower and more expensive in statically typed languages (Go, Rust, TypeScript, Java) than dynamic languages (Ruby, Python, JavaScript) for agentic coding tasks, with type checkers adding overhead but no measurable correctness benefit.

Quantitative experiment running Claude Code (Opus 4.6, high-effort mode) to implement a mini-Git across 13 languages, each trial repeated 20 times. Dynamic languages — Ruby, Python, and JavaScript — were fastest, cheapest, and most stable; statically typed languages (Go, Rust, TypeScript, C, Java) ran 1.4–2.6× slower and more expensive. Intra-language comparisons with mypy/Steep confirmed type-checker overhead adds real cost with no measurable correctness benefit in this agentic coding task.
