Replaces all children of the ParentNode with the passed-in nodes.


Previously, there are a couple different ways to replace a node's children with a new set of nodes. For example: 1. Use node.innerHTML = '' to clear out node's children and call node.append(nodes); Or: 2. Loop through node's children and call node.removeChild() on each one. Then call node.append(nodes). This replaceChildren API enables web developers to easily replace node's children without spending cycles on which way is best.
