1人 Intl Advent Calendar 2024 - Adventar
JavaScript(ECMAScript)の国際化API、「Intl」について紹介する1人 Advent Calendar です。 2024末時点でのIntl仕様と提案されているProposalを広く紹介することをゴールとしています。合わせてIntlに関連する仕様についても端端で紹介できたらなと思っています。 機能・ドメイン的に関連する話題をまとめて紹介していくので、「既存仕様→関連するProposal」の順で繰り返す流れになる予定です。基本的な機能だけ知りたいよと言う方は適宜読み飛ばしてください。
GitHub - lingui/js-lingui: 🌍 📖 A readable, automated, and optimized (3 kb) internationalization for JavaScript

Locale Aware Sorting in JavaScript
This post is part of my Byte Series, where I document tips, tricks, and tools that I've found useful. ProblemWhen building a localized JavaScript web-app, the default sorting logic for strings doesn't quite yield the results that you might expect. For example, take the following example… let strings = [ "nop", "NOP", "ñop", "abc", "abc", "äbc" ]; strings.sort(); console.log(strings); // ['NOP', 'a
Listify a JavaScript Array
Listify a JavaScript ArrayFebruary 18th, 2021 — 6 min read When you want to display a list of items to a user, I'm afraid .join(', ') just won't cut it: console.log(['apple'].join(', ')) // apple // looks good console.log(['apple', 'grape'].join(', ')) // apple, grape // nah, I want "apple and grape" console.log(['apple', 'grape', 'pear'].join(', ')) // apple, grape, pear // wut? Ok, so bust out y

Intl.NumberFormatでゼロ埋めや％表記などの数値表現を楽に実装する
Number#toFixed や Math.round/floor/ceil を駆使して表示用の値を整形することってないでしょうか。カンマ区切りをオレオレユーティリティ関数で実装したりそういったことを実現するライブラリを探したことはないでしょうか。 ほとんどの JavaScript の実行環境にはIntlという i18n のためのオブジェクトが組み込まれており、その中の１つにIntl.NumberFormatというクラスがあります。 オプションが色々あり、かなり便利で多機能なんですが整理された情報が少なく、身の回りで使用してる人も少ないと感じました。 Do you use Intl.NumberFormat? — れこ (@L_e_k_o) February 25, 2019 （2019/03/04あたりに結果表示されると思います。途中経過を見る場合元ツイートに飛んでください。） 「それ自
Intl.PluralRules · V8
Iñtërnâtiônàlizætiøn is hard. Handling plurals is one of many problems that might seem simple, until you realize every language has its own pluralization rules. For English pluralization, there are only two possible outcomes. Let’s use the word “cat” as an example: 1 cat, i.e. the 'one' form, known as the singular in English2 cats, but also 42 cats, 0.5 cats, etc., i.e. the 'other' form (the only
