How do I clear Rust, Go and other language build caches?

Q: How do I clear Rust, Go and other language build caches?

Most toolchains have a cleanup command: - Rust: cargo clean in a project removes its target folder, often the biggest item. - Go: go clean -cache clears build cache; go clean -modcache clears downloaded modules. - Conda: conda clean --all removes package caches and unused packages. - Python virtual environments: delete .venv folders in inactive projects and recreate them later. Everything here is regenerated by the next build or install.

Short answer: Use cargo clean for Rust target folders, go clean -cache and -modcache for Go, conda clean --all for Conda, and delete old .venv folders. All are regenerated later.
