Fastdom – a weapon in the war against jank

We're using this for http://app.ft.com, and it has completely eliminated problem of layout trashing for us.

We can have many independent components, each one independently reading and modifying DOM however it wants, but all of that goes asynchronously through fastdom that acts as a scheduler.

In Firefox: "Page load failed! The application could not be fully loaded. Please try again later."

But it loads in Chrome.

I get a very janky scroll on an iPhone 6s on this page. Presumably it's not thrashing though.

It used to be much much worse, to the point of being absolutely unusable on the latest iPhone. I actually cancelled my FT subscription for several years solely because of the poor performance of that site.

It still has a nice bug where it reserves space for ads, then when it fails to download them (because you're offline) after 60s the whole page reflows (losing your position). Plus the classic loss of scroll position on screen rotation.

I get error on your splash from note 2, unrelated? :)
