Scroll Event
Noun · Development
Definitions
A browser DOM event fired when the user scrolls an element or the page, notorious for triggering at extremely high frequency and requiring throttling or debouncing to avoid performance degradation.
In plain English: A signal the browser sends every time you scroll, which can fire so often it slows things down if handled carelessly.
Example: "We throttle the scroll event to 60fps; without it, the parallax handler was causing jank on every pixel of movement."
