58. get DOM tree height

Recursive Solution:

function getDOMTreeHeight(node) {  if (!node) {    return 0;  } else {    let leftHeight = getDOMTreeHeight(node.leftElement);    let rightHeight = getDOMTreeHeight(node.rightElement);        if (leftHeight > rightHeight) {      return leftHeight + 1;    } else {      return rightHeight + 1;    }  }}let treeHeight = getDOMTreeHeight(document.querySelector('div'));console.log(treeHeight);

Iterative Solution:

function getDOMTreeHeight(node) {  if (!node) {    return 0;  }    let queue = [];  queue.push({node: node, height: 0});  let maxDepth = 0;    while(queue.length > 0) {    let current = queue.shift();    let currentNode = current.node;    let currentHeight = current.height;        maxDepth = Math.max(maxDepth, currentHeight);        for(let i=0; i<currentNode.children.length; i++) {      queue.push({node: currentNode.children[i], height: currentHeight + 1});    }  }    return maxDepth;}let treeHeight = getDOMTreeHeight(document.querySelector('div'));console.log(treeHeight);
