Here is an implementation of smooth scroll that is cancellable by the user.
It was really annoying having my scroll constantly hijacked by the smooth scroll. (Macbook with trackpad - I was scrolling really slowly 馃槥)
To fix this, we use cause and effect. Programmatic scroll kicks in the scroll events, thus we remember what value we intended to smooth scroll to. If user initiates their own movement, this will show as a difference to our intended scroll position and therefore cancel our smooth scroll immediately.
On a side note:
That does make me wonder what would happen in a native snap scroll implementation world;聽What happens when your JS scrolls programmatically against a snap scroll enabled container, what does native snap scroll do in that situation?
