The term "Touchend" refers to an event in web development that occurs when a touch interaction, such as tapping or swiping on a touchscreen device, has concluded. This event is part of the Touch Events API, which allows developers to create responsive and interactive applications for devices like smartphones and tablets. When a user lifts their finger off the screen, the Touchend event is triggered, signaling that the touch gesture has ended. This event can be used to execute specific actions, such as navigating to a new page or triggering animations, enhancing the overall user experience on touch-enabled devices.
