What is event bubbling

Event bubbling is an event propagation mechanism in JavaScript. When an event is triggered on an element, the event will be processed on the element and passed to its parent element step by step over time. Passed to the root element of the document, this propagation process is called event bubbling. The process of event bubbling is similar to the process of water bubbles rising from the bottom to the surface. The event is triggered first on the deepest element and then propagates upward until it reaches the outermost parent element.
