Mouse events are actions that occur when a user interacts with a computer mouse. These events include movements, clicks, and scrolls, which can trigger specific responses in software applications. For example, when a user clicks on a button, a mouse event is generated, prompting the application to perform a designated action. In web development, mouse events are essential for creating interactive user interfaces. Common mouse events include mousedown, mouseup, click, and mousemove. Developers can use these events to enhance user experience by providing feedback, such as highlighting buttons or displaying tooltips when the mouse hovers over certain elements.
