FAQs

Event delegation has the following advantages in addition to reducing memory consumption:

When elements are added or withdrawn from the DOM, there is no need to manually manage events.
There is less code to maintain because there are fewer event handling functions.

When the mouse is put over an HTML element, the mouseenter event occurs, and when the mouse is removed from the element, the mouseleave event occurs.

When you click on an html element, the jQuery click event is triggered. The click event is triggered using the jQuery click() method. For instance, $("p"). When a paragraph on a document is clicked, click() will fire the click event (a web page).
