I consider myself a somewhat impartial observer in this debate, but I find it interesting nonetheless.

Made a new hook today, useGesture. Pretty useful for any type of low-level gesture access, tracks mouse/touch and deltas. The whole thing down there is roughly 10 lines of code, interaction and all. https://t.co/jNM5kRhCR2

Updated Component Lifecycle Methods docs! Detailed further how componentWillLoad() and componentWillUpdate() can return promises, and the order of which they're fired in the parent/child relationship is still maintained as they resolve: https://t.co/xuJUa0sdOF

AKA please go use lazy() and code split your application React folks!

If you don't think you need to lazy load, send me the URL for your app and we'll look at some profiles!!!!! 😍

.myEl,
.myEl:focus-within {
/* ... */
}

The `:focus-within` pseudo-class doesn't work on IE, as the CanIUse chart shows, thus the above CSS rule gets invalidated entirely according to specs.

"TL;DR"
Fancy new CSS selectors within groups of selectors can break your stuff.
