Event object
The Event object represents the state of the event, such as the element in which the event occurred, the state of the keyboard key, the position of the mouse, and the state of the mouse button.
Events are often used in conjunction with functions, functions will not be executed until the event occurs!
Event Handlers¶

1. Click event
2. Double click event
3. Mouse event
onmouseover: mouse put event
onmouseout: mouse leave event
onmousemove: mouse move event
4. Keyboard events
onkeydown: keyboard down event
onkeyup: keyboard up event
