How can I improve event handling performance in my application?

To improve event handling performance, consider debouncing or throttling events, optimizing your event listeners, and reducing the number of DOM manipulations.

What is debouncing and how does it help?

Debouncing is a technique that limits the rate at which a function is executed. It ensures that a function is only called after a certain period of inactivity, which can reduce the number of times an event handler is triggered.

Can you give me an example of when to use throttling?

Throttling is useful for events that fire continuously, like scrolling or resizing. It ensures that the event handler runs at a fixed interval, improving performance by preventing excessive function calls.

Are there any tools to help analyze event performance?

Yes, tools like Chrome DevTools can help you analyze event performance. You can use the Performance tab to record and inspect event handling times.
