Pointer Events are a set of events in web development that allow developers to handle user interactions with various input devices, such as a mouse, touch screen, or stylus. They provide a unified way to manage different types of input, making it easier to create responsive and interactive web applications. These events include actions like pointerdown, pointerup, and pointermove, which correspond to the pressing, releasing, and moving of a pointer device. By using Pointer Events, developers can create more versatile interfaces that respond to multiple input types without needing separate event handlers for each device.
