DOM Traversal: Navigating the HTML Tree
Source: developer.mozilla.orgintermediate
DOM traversal is navigating a family tree of HTML nodes. You move between elements using properties like `parentNode` and `nextSibling`. This is key for finding elements relative to a known start point.
Think of the DOM as a family tree for your HTML. Traversal is how you walk from one node to another using properties like `parentNode`, `childNodes`, and `nextSibling`. It's fundamental for finding a form that contains a clicked button or highlighting all siblings. The main footgun is that `childNodes` returns all node types, including whitespace text nodes, not just the `Element` nodes you usually want.
