A Pointer Event is a type of event in web development that allows developers to handle input from various pointing devices, such as a mouse, touch screen, or stylus. This event provides a unified way to manage different types of user interactions, making it easier to create responsive and interactive web applications. Pointer events include actions like pressing, moving, and releasing a pointer device. They are part of the W3C specification and can replace traditional events like mousedown, mousemove, and mouseup. By using pointer events, developers can simplify their code and improve the user experience across different devices.
