JavaScript のスクリプトインポートを正しく使い分けようという話
JavaScript の文脈で「スクリプトをインポートする」といった場合、色々な可能性が考えられます。現場での混乱を避けるためにも用語を正しく使い分ける必要があります。そこで本記事では JavaScript のスクリプトインポートについて整理します。 更新履歴 2019/12/05 Dedicated Worker の ES Modules サポートについて追記しました。 2018/09/08 Worklet の type とその上での dynamic import について追記しました。 Service Worker 上での importScripts について追記しました。 Classic Script と Module Script スクリプトインポートを理解するには、スクリプトについて正確に理解する必要があります。HTML の仕様では、スクリプトには Classic Script
An experimental data-flow analysis tool for front-end JavaScript
What is FromJS? FromJS shows you where each value in the DOM comes from. For example, some data might have been loaded using fetch, some might have been stored in localStorage, and some might have been hard-coded in the JavaScript code. Try FromJS I've not worked on this for a while and it never worked super well, so maybe you shouldn't actually try it :) Install from NPM: npm install -g @fromjs/c
新しいChromeでスクロールが取れない？ scrollingElement？ | Ginpen.com
知り合いに聞かれて気づいたんですが、Google Chromeのv61からスクロールの取得方法が変わったっぽい。とりあえずこんなコードで取れます。 なんだこれ Chrome 60までとか未対応のやつは document.documentElement.scrollTop が常に 0 を返すので、 || で繋げてやるとどっちに対応してる環境でも動きます。 事前にUAから分岐して要素を分けて、みたいなことしてると駄目なので、こっちがおすすめです。そんなに実行コストかからんでしょ。知らんけど。 Chromeは変わったけどSafariはまだ変わってないので、対応しときましょう。 あとEdgeも document.body の方みたい。IEは document.documentElement だったのに。はしごを外されちゃったね。 scrollingElement なるものが で、ちらちら見てたら
chromium/src - bbf870d971 — Implement Element.scrollIntoView for scroll-behavior: smooth.
Implement Element.scrollIntoView for scroll-behavior: smooth. Currently in Chrome, a call to Element.scrollIntoView will calculate the amount each scroller needs to scroll to align the Element as specified and instantly set the scroll position on that scroller (going from the innermost to the outermost scroller). If Element.scrollIntoView is called with scroll-behavior: smooth, instead of scrollin
Using requestIdleCallback | Blog | Chrome for Developers
Many sites and apps have a lot of scripts to execute. Your JavaScript often needs to be run as soon as possible, but at the same time you don’t want it to get in the user’s way. If you send analytics data when the user is scrolling the page, or you append elements to the DOM while they happen to be tapping on the button, your web app can become unresponsive, resulting in a poor user experience. Th

Big boost to DOM performance - WebKit's innerHTML is 240% faster | Blog | Chrome for Developers
We're very happy to see that some common DOM operations have just skyrocketed in speed. The changes were at the WebKit level, boosting performance for both Safari (JavaScriptCore) and Chrome (V8). Chrome Engineer Kentaro Hara made seven code optimizations within WebKit; below are the results, which show just how much faster JavaScript DOM access has become: DOM performance boosts summary div.inner
