Deno
公式: Deno, the next-generation JavaScript runtime
Deno は、V8 JavaScriptエンジン及びRustプログラミング言語に基づいた、JavaScript及びTypeScriptのランタイム環境である。
Node.js の作者であるライアン・ダールによって作成され、セキュリティと生産性に焦点を当てている。
ライアン・ダールが 2018 年に行った講演「Node.jsに関する10の反省点」で発表された。
Deno は単一の実行ファイル内でランタイム環境とパッケージ管理システムの両方の役割を明示的に引き受けるので、別途パッケージ管理システムを必要としない。
