In the event bubbling example, what element is considered the event target when the button is clicked?

When a button is clicked, the event target is the element that triggered the event, which in this case is the button itself. The concept of event bubbling refers to the process whereby an event starts from the target element and then bubbles up to its parent elements in the DOM tree, triggering the event handlers of those parent elements in the order of their hierarchy.

Understanding this is crucial because it highlights the behavior of events in the Document Object Model (DOM). During this process, while the button is indeed the event target, the outer div and inner div can also have their own event handlers that might be executed as the event bubbles up. However, these parent elements are not considered the target of the event; they merely respond to the event as it propagates.

The choice that suggests an array of all nested elements is not accurate in the context of defining a single event target. In event handling, the target is specifically the element that was interacted with, which clearly identifies the button as the correct choice. This understanding is essential in building applications that respond to user actions effectively, allowing developers to manage and manipulate events correctly within the DOM structure.
