Description: Event capturing is a phase of event propagation in the Document Object Model (DOM) event model in JavaScript. In this phase, the event starts from the root node of the document and descends through the hierarchy of nodes until it reaches the target element that triggered the event. This process allows event handlers to be registered at different levels of the DOM hierarchy, providing great flexibility in event management. Event capturing is part of the event propagation model, which also includes the bubbling phase, where the event ascends from the target element back to the root node. The ability to intercept events during the capture phase allows developers to implement specific logic before the event reaches the target element, which can be useful for validation or event manipulation. This feature is especially relevant in web applications where multiple elements may be listening for the same event, and precise control over the event flow is required. In summary, event capturing is a powerful tool in JavaScript that enables developers to effectively manage user interaction with the user interface.
