Somebody on /r/ posted this.
I just read it. I can't believe this patent was granted. If I'm reading it correctly, it's a patent for an old trick used by every OS and video game ever made. Basically, don't redraw things that aren't in view, and only redraw the bits of things that are in view.
Anyway, I can't see how this is applicable to React, as it really isn't how the v-dom works at all. The v-dom isn't about failing to draw clipped items. The v-dom is about diffing two trees and only updating changed items.
Am I totally off base here?
