What is a key benefit of using WeakSet over Set for DOM element tracking?
WeakSet's benefit for DOM tracking: 1) It allows DOM elements to be garbage collected when removed from the document, 2) This prevents memory leaks in single-page applications, 3) No manual cleanup is needed when elements are removed, 4) The WeakSet automatically maintains itself as the DOM changes, 5) This is particularly valuable in dynamic web applications, 6) It prevents accidentally keeping references to removed DOM elements, 7) The pattern works well with virtual DOM and component lifecycles, 8) It demonstrates practical application of weak references in web development.
