implementing Throttling Event Listeners in React - Unexpected Multiple Executes
I'm working on a personal project and This might be a silly question, but This might be a silly question, but I'm working with an scenario with throttling event listeners in my React application... I implemented a throttle function to limit the number of times a scroll event handler executes. However, I'm observing that the function gets called more frequently than expected, causing performance degradation during rapid scrolling. Here's the throttle function I'm using: ```javascript function throttle(func, limit) { let lastFunc; let lastRan; return function() { const context = this; const args = arguments; if (!lastRan) { func.apply(context, args); lastRan = Date.now(); } else { clearTimeout(lastFunc); lastFunc = setTimeout(() => { if ((Date.now() - lastRan) >= limit) { func.apply(context, args); lastRan = Date.now(); } }, limit - (Date.now() - lastRan)); } }; } ``` I attach this throttle function to the scroll event like this: ```javascript useEffect(() => { const handleScroll = throttle(() => { console.log('Scroll event triggered'); }, 100); window.addEventListener('scroll', handleScroll); return () => { window.removeEventListener('scroll', handleScroll); }; }, []); ``` The question occurs when I scroll quickly; I see multiple 'Scroll event triggered' logs in the console, suggesting that the throttle function isn't working as intended. I've tried debugging by simplifying the throttle function and logging the timestamps, but it seems that the function is still being executed more than once within the throttling window. I've also tested it on different browsers and devices, but the scenario continues. Any insights on what could be going wrong or how to properly implement throttling in this context would be greatly appreciated! For context: I'm using Javascript on Ubuntu. How would you solve this? I'm working on a CLI tool that needs to handle this. Any ideas what could be causing this? Any examples would be super helpful.
