A common UI pattern for a range slider is to allow the user to move the slider and display the value of it somewhere on the page, changing the displayed value as the user moves the slider.
I think the expected behaviour in such a case is that the value should display instantly, as the user is moving the slider, rather than the page waiting for the slider to finish moving before the displayed value is updated. I suppose there could be cases where you prefer a delay over instant results, but I think the expected behaviour is to display the results instantly.
As you’ll see in the videos below and in your own testing, the behaviour of the
input event compared to the
change event is not exactly the same in different browsers when applied to a range slider.
