Release v0.21.0 · evanw/esbuild
This release doesn't contain any deliberately-breaking changes. However, it contains a very complex new feature and while all of esbuild's tests pass, I would not be surprised if an important edge case turns out to be broken. So I'm releasing this as a breaking change release to avoid causing any trouble. As usual, make sure to test your code when you upgrade. Implement the JavaScript decorators p

ECMAScript Module Harmony
Module Harmony とは 現在 TC39 で多くのモジュール機能を追加する提案が進行しています。かつてはそれぞれの提案が無秩序に進行していましたが、2023年5月に Module Harmony として整理されました。この記事ではそれら提案についてまとめようと思います。 モジュール提案仕様の依存関係 インポートフェーズ修飾子 モジュールの読み込みがフェーズに分けられ、それぞれに対して修飾子が提案されています。シンタックスとしては import の後ろに修飾子を付けます。 import <Modifier> <ImportBinding> from <ModuleSpecifier>; import.<Modifier>(<AssignmentExpression>); モジュールの各フェーズと修飾子の対応 アセット参照 URL やパス解決のみをするのがアセット参照です。Asset
Explicit Resource Management: Exploring JavaScript's and TypeScript's new feature | iliazeus
Explicit Resource Management: Exploring JavaScript's and TypeScript's new feature 2023-11-13 en CC BY-SA 4.0 read in russian One of my favorite new features of JavaScript and TypeScript is explicit resource management.

Unique identifiers for Japanese calendar eras · Issue #526 · tc39/proposal-temporal
In all our pseudocode examples supposing a Japanese calendar thus far, we've been passing in era names as lowercased ASCII string identifiers made from English transliterations of the names, e.g. { year: 2, era: 'reiwa' } for the current year. That requires that these identifiers are unique. However, that seems not to be the case as there are several eras written with different kanji but with the
Temporal API is Awesome · Taro
Wednesday, August 23, 2023 Dates in JS suck. Well, they suck in all languages, really. It's surprisingly hard to get right. The native Date is super limited. Sure, you can new Date('2015-10-21T01:22:00.000Z') and date.toISOString(), maybe dateA < dateB, but that's pretty much it. Need to add minutes, hours, or whatever to a date, check how many days there are until X date, etc? Good luck with that

GitHub - endojs/Jessie: Tiny subset of JavaScript for ocap-safe universal mobile code
This document is an early draft. Comments appreciated! Thanks. Today, JavaScript is the pervasive representation for (somewhat) safe mobile code. For another representation to achieve universality quickly, it must be a subset of JavaScript, and so runs at least everywhere JavaScript runs. Whereas JSON is a simple universal representation for safe mobile data, Jessie is a simple universal represent

var / let / const と言う脈略のない三銃士ども · Ubugeeei/work-log · Discussion #136
序 ここ数日、for文の由来は何か? と言う話題が上がった。 シンタックスのキーワードの由来については自分も関心があって、好きなトピック。 中でも、いつも思っていたことがあって、JavaScriptの変数宣言に使われるキーワード選定が謎と言うのがある。 このことについてツイートしたところたくさんの方に反応をいただけたので備忘録として。 元ツイ: https://twitter.com/ubugeeei/status/1691491304428236800?s=20 お気持ち: https://twitter.com/ubugeeei/status/1691623230812123376?s=20 その他お気持ち: https://twitter.com/ubugeeei/status/1691519021957672961?s=20 https://twitter.com/ubugeeei
