    Synthetic Events are events that are created by the browser to mimic real user events.

    • Synthetic Events are used in React to handle events in a consistent manner across different browsers.

  • Answered by AI
  • Q2. What is event bubbling?
  • Ans. 

    Event bubbling is the process where an event triggered on a child element is propagated up through its parent elements.

    • Event bubbling allows a single event handler to be attached to a parent element, which will be triggered for all its children.

    • When an event occurs on a child element, it first runs the event handlers on the child, then on its parent, and so on up the DOM tree.

    • Event bubbling can be stopped using event.s
