About the project

Deno is JavaScript and TypeScript runtime with built-in tooling and a stricter security model. The maintainers own the project, choose releases, and publish their own documentation. This page records a few things worth knowing before you begin.

Governance sits with the project's own team. They decide what ships, how often it ships, and which platforms are supported.

Typical distribution routes

There is no single universal route here. Maintainers usually describe the supported options themselves, and the choice varies between platforms and between releases.

Platform requirements

Confirm the platform is supported by the current release. Tooling in this space moves quickly, and an older system often falls outside the supported range.

Checking the result

Most surprises here come down to path ordering or to two copies being present at once. Checking which one resolves first usually explains the difference.
