Dart について

• Google製
  • 一部ECMAになってる（古い時代の仕様）
• 型あり（基本静的型付けだけど、動的型付けも可能。型推論もある）
• 最新Version: 2.17.0
• インタプリタ(CLI等）とコンパイラ（スマホ用ビルド等）がある
• 元々はWeb用のスクリプト言語用途で開発、JSにコンパイル可能(2011年～)
• Flutterに採用されてブレイク
  • 【翻訳記事】なぜFlutterにおいてDartを使用するのか？ - Qiita https://qiita.com/yasutaka_ono/items/608405a27e57cc30e0d7
    • 静的言語と動的言語のいいところどり
