TouchMove is a JavaScript event that occurs when a user moves their finger across a touch-sensitive screen. This event is part of the Touch Events API, which allows developers to create interactive applications for devices like smartphones and tablets. It provides real-time feedback as users swipe or drag their fingers, enabling smooth and responsive user experiences. When a TouchMove event is triggered, it can be used to track the movement of a user's finger and respond accordingly. Developers can implement features such as scrolling, dragging, or drawing on the screen, enhancing the overall functionality of touch-enabled applications.
