I've been working a lot with building react components recently that support gesture controls - things like swipe to open / close, pinch to expand... basically, all of the stuff that is standard in native apps but is relatively rare on the web.
My conclusion: It's actually quite possible... and FUN! So much fun, in fact, that I got carried away with a little demonstration app. I thought, what better way to prove that advanced gestures are possible on the web than by reimplementing the iOS home screen functionality?
So here it is: react-iphone.
Try long pressing an icon to enable drag and drop. Swiping up, down, left or right at various parts of the screen will trigger some of the behavior that you expect in iOS. It's not all there, but I think it proves the point.
It works pretty well in iOS Safari too (just enter full screen)! Haven't had the chance to try android yet, so I'd love to get some feedback there.
One of the most consolidated misconceptions about programming, since the early days, is the idea that such activity is purely technical, completely exact in nature, like Math and Physics. Computation is exact, but programming is not.
