The "TouchEnd" event is part of the Touch Events API in web development. It occurs when a touch point is removed from the touch surface, such as when a user lifts their finger off a touchscreen device. This event is crucial for detecting the end of a touch interaction, allowing developers to trigger specific actions or animations in response. In addition to TouchEnd, there are other related touch events, including TouchStart and TouchMove. These events work together to provide a complete touch interaction experience. By handling these events, developers can create more responsive and engaging applications for mobile and tablet users.
