A user can enter a continuous stream of input as they type, resize, or scroll through your app. If any of these actions feel sluggish you’ll likely hear complaints and lose users. Expensive handlers for these actions can bog your app down and make it feel unresponsive. Debouncing minimizes this problem by limiting how often a function can fire and keeping your app responsive.
