Would love to know how this was done.
I think the more concerning call would actually be some crazy selector, animation, and implicit state change which could be done in just a few calls that happen rarely.
With this in mind I think the right metric is #call-sites and not #calls: most of the time the effort required to refactor a jquery call away is not proportional to the number of times the function is called.
Does Github use TypeScript?
My concern, also when building UI with React, is that web design is often only interested in end-state of an interface, playing a bunch of fire-and-forget animations to transition between states.
The reality, that only games and Apple seem to have embraced, is that it's far more sophisticated for animation to reflect a state that can change at 60 or even 120 frames per second, depending on what the user is doing.
This is a great presentation from Apple, Designing Fluid Interfaces, that captures the concept: https://developer.apple.com/videos/play/wwdc2018/803/
Am curious: have any web frameworks embraced this approach?
The gestures and animations in that video are a million miles away from the best I’ve seen on the web.
