Deno

Provides an open-source JavaScript and TypeScript runtime that runs Node-compatible code and removes the need for separate configuration of TypeScript compilation, bundling, and tooling. Targets software developers and engineering teams in businesses that build and deploy JavaScript applications. Positioned as faster than Node and more stable than Bun, with built-in package management, testing, linting, and formatting instead of external toolchains, delivered as an installable runtime and optional serverless hosting platform.
