Example usage
function getDOMDepth(node) {
if (!node) return 0;
if (node.nodeType !== 1 && node.nodeType !== 9) return 0;
const children = node.children || [];
if (children.length === 0) return 1;
let maxDepth = 0;
for (let i = 0; i < children.length; i++) {
maxDepth = Math.max(maxDepth, getDOMDepth(children[i]));
}
return 1 + maxDepth;
}
// Example placeholder (requires DOM environment)
// console.log(getDOMDepth(document.documentElement));05
