This rule counts the number of DOM-accessing functions calls on a scroll event, such as queries, readings, writings, bindings and jQuery functions.
Two scroll events are triggered quickly, one after the other, and only the second one is analyzed so throttled functions are ignored.
One of the main reasons of a poor scrolling experience is when too much JS is executed on each scroll event. Note that some devices such as smartphones and MacBooks send more scroll events than others.
Reduce the number of DOM accesses inside scroll listeners. Put DOM queries outside them when possible. Use throttling or deboucing.
