Mouse Events

This video tutorial covers various mouse events in JavaScript, including click, double click, mouse down, mouse up, mouse enter, mouse leave, mouse over, mouse out, and mouse move. It explains how to create event handlers and use them to log event types. The tutorial also demonstrates how to use mouse coordinates to create interactive effects, such as changing background colors and displaying mouse coordinates in real-time.

• To change the background color based on mouse coordinates

• To create new HTML elements

What is the purpose of using RGB values in the context of the 'mouse move' event?

• To set the text color of an element

• To log the mouse coordinates

• To change the background color dynamically

• To create a new HTML element
