Dart 會編譯成 JavaScript，有時產生程式碼的速度比手寫 JavaScript 更快。觀看 Dart 共同創辦人 Kasper Lund 說明 dart2js 編譯器如何執行本機和全域最佳化作業，藉此發出快速且語意上正確的 JavaScript 程式碼。Dart 使用樹狀搖頭、推論和壓縮功能，幫助您將網路應用程式最佳化。

It uses techniques like tree shaking, removing unused code, type inference to deduce data types, and minification to reduce code size. These optimization methods ensure that the JavaScript code generated from Dart is both semantically accurate and highly performant, ultimately improving web app performance.\n"]]
