Custom Scroll Handling and Event Debouncing
Provide an example of custom scroll event handling using TanStack Virtual, including how to debounce scroll events to optimize performance.
const debounce = (func, wait) => {
let timeout;
return function executedFunction(...args) {
const later = () => {
clearTimeout(timeout);
func(...args);
};
clearTimeout(timeout);
timeout = setTimeout(later, wait);
};
};
This function creates a debounced version of a passed function. It delays the execution of the function until after wait milliseconds have elapsed since the last time it was invoked.
const handleScroll = debounce(() => {
console.log('Scroll event debounced.');
// Your logic to handle the scroll event
}, 200);
This creates a debounced version of the scroll event handler. It utilizes the debounce function to limit how often the handler is called during scroll events, boosting performance.
window.addEventListener('scroll', handleScroll);
This adds an event listener to the window object that listens for scroll events and calls the debounced scroll event handler.
