Okay, let me get this out of the way real quick. I hate websites that attach wheel (or touchstart and touchmove) events to a page. Utterly hate them. The main reason is the horrid resulting performance, especially on mobile. You see, the browser has to wait to redraw the page until the event listener finishes execution, as the event is able to be canceled. If your event runs on every single scroll
TL;DRChrome 60 reduces jank by lowering event frequency, thereby improving the consistency of frame timing. The getCoalescedEvents() method, introduced inChrome 58 provides the same wealth of event information you've had all along. Providing a smooth user experience is important for the web. The time between receiving an input event and when the visuals actually update is important and generally

We know that scrolling responsiveness is critical to the user's engagement with a website on mobile, yet touch event listeners often cause serious scrolling performance problems.Chrome has been addressing this by allowing touch event listeners to be passive (passing the {passive: true} option to addEventListener()) and shipping the pointer eventsAPI. These are great features to drive new content
Great applications do not lose user's progress and app state. They automatically save thenecessary data without interrupting the user and transparently restore themselves as and whennecessary - e.g. after coming back from a background state or an unexpected shutdown. Unfortunately, many web applications get this wrong because they fail to account for the mobile lifecycle: they're listening for t

After I prototype an app I'mbuilding, my time is split between the editor and the browser with the console open. I try to debug as Igo to avoidcreating a complete mess. Moreover, when I get a bugreport for a production app the first thing that I do is try to debug usingChrome devtools, and I usually find the bug without touching my editor. To be effective at that, I had to learn a great deal
Updated 2014.10.15 / Published 2014.03.04 ホイール系のイベントは各ブラウザの実装がバラバラでクロスブラウザ対策に苦労するイベントのひとつとして知られているでしょうが、Document Object Model Level 3 Eventsにより標準化されたwheelイベントが多くのブラウザで実装されてきています。本エントリーでは現状のホイール操作時の各イベントについて、クロスブラウザでフォールバックしながら用いる方法を解説していきます。 ホイール系イベント比較 DOMMouseScroll, MozMousePixelScroll DOMMouseScrollイベントとMozMousePixelScrollイベントはどちらもGecko 固有のため、現存ではFirefoxしかサポートしていないイベントです。DOMMouseScrollはスクロールする
