14. async event handler

The code outputs "0" twice in the console log. This is because when the App component is first rendered, the initial state value of 0 is logged. Then, whenever the "click me" button is clicked, the increment function is called, which schedules a state update by calling setState inside a setTimeout with a delay of 0ms. This means that the state update will be processed after the current event loop is finished. Therefore, the two clicks on the button schedule two separate state updates, but since they happen within the same event loop iteration, the state is only updated once, from 0 to 1. So, the second click does not result in a state change, and the console log outputs 0 again.
