マイクロソフト、JavaScriptに型宣言を追加しつつトランスパイラ不要の「Types as Comments」をJavaScript仕様策定会議のTC39に提案へ
マイクロソフト、JavaScriptに型宣言を追加しつつトランスパイラ不要の「Types as Comments」をJavaScript仕様策定会議のTC39に提案へ マイクロソフトのTypeScript開発チームは、JavaScriptのコードにTypeScript互換のアノテーション（注釈）を加えることで変数や関数などの型を宣言し、エディタなどのツールで型情報を活用可能にする一方、実行時にはJavaScriptエンジンがアノテーションを無視することでコードをトランスパイラで変換することなく実行可能なJavaScriptの新構文「Types as Comments」を、JavaScriptの使用を策定する「TC39」（Ecma International, Technical Committee 39）に提出する計画を明らかにしました。 このマイクロソフトの発表には、TC39の共同議長で
Node.jsの作者であるライアン・ダール（Ryan Dahl）氏が新たに立ち上げ、サーバサイドでJavaScript/TypeScriptを実行するためのオープンソースのフレームワーク「Deno」と、その分散ホスティングである「Deno Deploy」を提供する「Deno Company」はECMAインターナショナルに加盟し、JavaScriptの標準化を行うTC39ワーキンググループに参加することを発表しました。 Deno has joined @EcmaIntl's @tc39: the JavaScript standards committee.https://t.co/meFUKD5KKG — Deno (@deno_land) December 13, 2021 DenoはTC39ワーキンググループの参加によって、JavaScriptを誰にとってもよいものに改善していくととも
JavaScriptを定義する。 TC39 Ecma InternationalのTC39は、JavaScript開発者、実装者、専門家などのグループで、JavaScriptの仕様をメンテナンスし発展させるためにコミュニティと協力しています。 我々は 所属の委員会です。 コントリビュート 既存のプロポーザルに対するフィードバック、ドキュメントの改善、テスト、実装、さらには言語機能に関するアイデアなど、JavaScriptコミュニティからのコントリビュートをTC39は歓迎します。詳細については、コントリビュータガイドをご覧ください。 TC39のミーティングにメンバーとして参加するには、Ecmaに参加してください。 仕様 我々はJavaScript(正式には、ECMAScript)の仕様をGitHub上で開発し、2ヶ月ごとにミーティングを行い、プロポーザルについて議論しています。このプロセスの
Intro TC39 の Stage 2 と Stage 3 の間に、新たに Stage 2.7 が追加された。 これは何だろうと思った人が検索で辿り着けるよう、その経緯と目的をまとめる。 TC39 Stages TC39 は、ECMAScript (つまりまあ JS) の新機能を議論する Task Group だ。 ここでは、比較的自由に新機能の提案がなされ、定期的に行われるミーティングでの議論や、実装からのフィードバックを経て、Stage が上がっていく仕組みをとっている。 旧来の Stage は 0~4 まであった。ざっくり言うと以下のようなものだ。

Deno aims to be the best runtime for the modern JavaScript developer. One way we do this is by embracing the latest in JavaScript standards. Deno is fundamentally built for modern JavaScript: Promises, async/await, ES modules and async iterators are all first-class citizens. To make sure that future evolutions of JavaScript will continue to work well for Deno - and server-side JavaScript runtimes

On MouseEvent we are interested on 'ctrlKey', 'shiftKey', 'altKey', 'metaKey' events only. We have a configObject and we need ['dependencies', 'devDependencies', 'peerDependencies'] from it. We have an optionsBagand we would allow on ['shell', 'env', 'extendEnv', 'uid', 'gid'] on it. Fro

sititou70です．少し未来のJavaScriptを紹介します！ Temporalは，TC39で提案されている次世代の日付APIです．現状のDateにおける欠点を克服するために，仕様を目下策定中です． tc39_studyというイベントで，TemporalについてのLTをしました．また，そのLTを行うにあたって，勉強のためにTemporalのドキュメントを翻訳していたのですが，そちらが公式リポジトリにマージされました 🎉 1分でわかるTemporal tc39_studyは，TC39の各プロポーザルを わずか30〜90秒でLTし続ける というヤバいイベントです．以下が私のLTのアーカイブです．（カミカミですが許してください） なお，このイベントの終盤は30秒LTゾーンという魔境となっており，面白いのでおすすめです．当日のTwitterも，「早口オタク」「情報の嵐」「処理が追いつかない

Shared structs have additional restrictions and can be concurrently accessed from different agents. Both unshared and shared structs have the following properties: Opaque storage like plain objects.

GitHub - tc39/proposal-decimal: Built-in decimal datatype in JavaScript
Accurate storage and processing of base-10 decimal numbers is a frequent need in JavaScript. Currently, developers sometimes represent these using libraries for this purpose, or sometimes use Strings. Sadly, JavaScript Numbers are also sometimes used, leading to real, end-user-visible rounding errors. What’s the issue? Why aren’t JS Numbers good enough? In what sense are they not “exact”? How is i
In this TC39 meeting, the updates to JavaScript Classes around private state have moved to stage 4. Other proposals of note this meeting were proposals related to ArrayBuffers, notably resizable ArrayBuffers and a new proposal, introducing read-only ArrayBuffers and fixed views into ArrayBuffers. Read-only ArrayBuffers are not a new ArrayBuffer, but rather a way to freeze existing ArrayBuffers so

I want to take some time to share everything I know about the pipeline operator proposal that is currently in stage 2, to the best of my ability. This will, of course, be a somewhat biased account — it's my article, haha — but I'll do my best to present both sides while presenting my case. Also, keep in mind, that as thorough as I'll try to be, I'm completely sure I'm missing things. If you spot s
