Tests:

treeWalker with param
const treeWalker = document.createTreeWalker( document.body, NodeFilter.SHOW_ELEMENT ); const list = []; while (treeWalker.nextNode()) { list.push(treeWalker.currentNode); }
treeWalker with filter function
const treeWalker = document.createTreeWalker( testTemplate.content, NodeFilter.SHOW_ALL, { acceptNode(node) { if (node.nodeType === Node.ELEMENT_NODE | Node.TEXT_NODE) { return NodeFilter.FILTER_ACCEPT; } return NodeFilter.FILTER_REJECT; } } ); const list = []; while (treeWalker.nextNode()) { list.push(treeWalker.currentNode); }
querySelectorAll
const list = document.body.querySelectorAll('*');
