How to install deno

Deno is a runtime for modern JavaScript and TypeScript with stricter defaults. Treat this as an orientation note. Anything prescriptive should come from the maintainers directly.

Paths onto a machine

Expect differences between platforms. The same project may reach one system through a package index and another through a source build.

Who is behind it

Ownership sits with the project's own contributors. Release cadence, supported platforms and documentation are all decided by them, and none of it is mediated here.

Before touching anything

Start from the support matrix. It narrows over time, and assumptions made years ago often no longer hold.

Reading the outcome

When results differ from expectations, check what is actually being picked up. Duplicate copies and stale caches are the usual explanation.

What this domain is

Only text is published from this domain. Each project remains exactly where its authors put it.

On reading release notes

Release notes are the cheapest way to catch a breaking change before it surprises you. They usually list platform shifts and removed defaults in the first few lines.
