The WheelEvent interface represents events that occur due to the user moving a mouse wheel or similar input device.

This is the standard wheel event interface to use.

Old versions of browsers implemented the two non-standard and non-cross-browser-compatible MouseWheelEvent and MouseScrollEvent interfaces. Use this interface and avoid the latter two.
