deno is a modern Javascript runtime that can run Javascript and Typescript natively. But it is also something that's available to all Python users without the need to install node.

You can run Deno, the modern JavaScript/TypeScript runtime, directly from a Python environment using `uvx deno` — no Node.js installation required. This is useful for running simple JavaScript unit tests (e.g., with happy-dom) or as a task runner via `uvx deno task build`, letting Python developers skip the Node toolchain for lightweight JS use cases.
