A "Touch Event" refers to a user interaction that occurs when a finger or stylus touches a touchscreen device, such as a smartphone or tablet. These events can include actions like tapping, swiping, or pinching, which allow users to navigate applications and interact with content on the screen. Touch events are essential for creating responsive and engaging user interfaces. In web development, touch events are part of the DOM (Document Object Model) and can be captured using JavaScript. They include specific types like touchstart, touchmove, and touchend, which help developers create applications that respond to user gestures. This enhances the overall user experience on touch-enabled devices.
