Deno is secure by default (a script must explicitly request network, filesystem or other access), supports TypeScript natively, uses Web standards (fetch, ESM, Web APIs) and ships with its own tooling (formatter, linter, test runner, bundler).

Version 2 (2024) brought full npm compatibility and serverless deployment through Deno Deploy, making it a serious option for the edge and modern tooling.
