Which property of an event object contains information about the target element that triggered the event?

The property of an event object that contains information about the target element that triggered the event is "target." This property specifically refers to the element that initiated the event, which can be different from the current element that is being handled if event delegation is used.

For example, if an event handler is attached to a parent element but the event is triggered by a child element within that parent, the target property will refer to the child element. This is crucial for JavaScript developers as it allows them to discern which specific element was interacted with, facilitating more dynamic and context-aware responses to user actions.

The other options relate to elements in different scopes. The currentTarget property refers to the element to which the event handler is currently attached, which may not always be the same as the target. The source and origin options do not exist in standard event objects in this context, making them irrelevant for identifying the element that triggered the event. Understanding the role of the target property is essential for managing events effectively in JavaScript.
