When interacting with a web page, the browser creates an event object to describe the action and sends it to the code.Event delegation in JavaScript relies on the structure of the DOM, the Document Object Model.Events in the browser follow a journey: top-down, target, and then up again.Event listeners in the capturing phase can be set with the third argument as true.Event delegation involves setting up a single listener on a parent element to handle events from its children.Delegation simplifies handling multiple dynamically generated elements without the need for individual listeners.Delegation allows for efficient event handling on elements that may not be present on the page initially.Using closest in event delegation allows for flexibility in handling events on nested elements.Delegation works with various events that bubble up through the DOM, such as input, change, and keyup.Event delegation offers control over which elements trigger specific actions, based on event target attributes.
