Learn how tomap over async/await operations in three different approaches. Have you recently run into the issue where you expected the result of yourmap function to return a resolved/awaited value, butit returned a list of promises. For example: const result = ids.map(async (id) => { return await fetch(id); }); //expected: [{name: "Adam"}, {name: "Linda"}] //actual result: [Promise {<pending>},
This post is for people who are familiar withJavaScript’s == operator.JavaScript’s “double equals” operator, ==, is typically discouraged. And forgood reason:its behavior is tricky. Where === asks “are these the same thing?”, the double-equals operator asks a question that’s not straightforward.

2024年10月のTC39ミーティングでは、Iterator HelpersがStage 4となり、ECMAScriptの仕様に追加されることが決定しました。Iterator HelpersはすでにGoogleChromeなどで試すことができます。Iterator Helpersは概してわかりやすい機能群ではありますが、やはり元々がJavaScriptということで、直観的には理解しがたい挙動もあります。そのような挙動は、とくにイテレータを分岐させたときに見られます。 ということで、この記事ではイテレータを分岐させた場合の挙動を見ていきましょう。Iterator Helpersそのものに関する基礎的な説明は省略していますので、他の記事をご覧ください。 イテレータを分岐させるIterator Helpersは、イテレータに生えたメソッドであり、返り値は新しく作られたイテレータです。そのた

Node.js で型安全な環境変数を扱うスニペットを作りました。 next devのようなアプリケーションの起動、Playwright でのテストなどコマンドごとに渡したい環境変数のセットが異なるケースがあります。 この場合に環境変数をまとめたものを定義して、それをコマンドごとに読み込むセットを変えたいことがあります。 次のようにベタ書きしてもいいのですが、渡したい環境変数が増えると管理が大変になります。 NEXT_PUBLIC_LOCALHOST_URL=http://localhost:3000 NEXT_PUBLIC_API_URL=http://localhost:3001 NEXT_PUBLIC_IS_TEST_MODE=false FOO="bar" next dev そのため、.envのような環境変数をまとめたファイルを使いたくなります。 Node.js は--env-fil
