Summary

Events in React are used to trigger functions based on user actions, such as clicking a button, and involve concepts like event delegation, propagation, capturing, and bubbling. Event delegation allows a single event listener on a parent element to manage events from its child elements, optimizing performance by reducing the need for multiple listeners. React uses SyntheticEvents to provide a consistent interface across different browsers, abstracting native DOM events. The article discusses the significance of the `event.stopPropagation()` method, which prevents events from propagating to parent elements, resolving potential conflicts between parent and child event handlers. It also highlights changes between React v16 and v17, where event delegation moved from the Document node to the root DOM container, improving event handling in nested React trees.
