Parent & Child Navigation
Navigate between parent and child elements in the DOM tree
javascript
// Parent access
const parent = element.parentElement
const parentNode = element.parentNode
// Children access
const children = element.children // HTMLCollection
const childNodes = element.childNodes // NodeList (includes text)
// First and last child
const first = element.firstElementChild
const last = element.lastElementChild
// Check for children
if (element.hasChildNodes()) {
// Has child nodes
}💡 children returns only elements, childNodes includes text
📌 closest() is great for event delegation
⚡ parentElement is null for document
✅ Use contains() to check relationships
