メモ: この記事のコンテンツは現在不完全です。申し訳ありません！私たちは MDN ウェブ開発の学習の章の改善に努めており、間もなく、 ("TODO") とマークされた場所も完了する予定です。 このレッスンでは、JavaScript のデバッグ（「何が間違っている?」で最初に見た内容）に戻ります。ここでは、エラーを特定するためのテクニックをさらに深く掘り下げていきますが、同時に、問題に直面する前に避けるために、防御的にコードを作成し、コード内のエラーを処理する方法も見ていきます。 前提知識:

Red Dirt JS
This document provides a summary of Nathan Smith's upcoming presentation on the future of HTML, CSS, and JavaScript.
