# Built-in tooling Deno provides some built in tooling that is useful when working with JavaScript and TypeScript: - [bundler (`deno bundle`)](./tools/bundler.md) - [debugger (`--inspect, --inspect-brk`)](./tools/debugger.md) - [dependency inspector (`deno info`)](./tools/dependency_inspector.md) - [documentation generator (`deno doc`)](./tools/documentation_generator.md) - [formatter (`deno fmt`)](./tools/formatter.md) - [test runner (`deno test`)](./testing.md) - linter (`deno lint`) [coming soon](https://github.com/denoland/deno/issues/1880)
