How do event listeners affect performance in web applications?
Event listeners can significantly impact performance, especially if there are many of them or if they are not managed properly.
What are some best practices for using event listeners?
Best practices include debouncing, throttling, and removing listeners when they are no longer needed.
Can you explain debouncing and throttling?
Debouncing ensures a function is only called after a certain period of inactivity, while throttling limits the number of times a function can be called over time.
How can I measure the performance impact of my event listeners?
You can use performance profiling tools in browsers, like Chrome's DevTools, to analyze event listener performance.
