What is the best practice for optimizing event handler performance?
Event delegation provides performance benefits through: 1) Reducing the number of event handlers in the application, 2) Better memory usage with fewer handler attachments, 3) Improved performance for dynamic content, 4) Efficient handling of multiple similar elements, 5) Reduced initialization time for large DOMs, 6) Better garbage collection patterns, 7) Simplified event management code, 8) More scalable event handling approach.
