Answer

Event capturing is the phase where listeners run along the event path before the target phase. • A listener opts into capture with the capture option. • The path proceeds from outer ancestors toward the target. • Capture is useful when an ancestor must observe an event before target and bubble listeners.

Example

Code

document.addEventListener('click', handleClick, { capture: true });
