Tests:

TreeWalker
const walker = document.createTreeWalker( document.body, NodeFilter.SHOW_ELEMENT, ); for (let node = walker.nextNode(), i = 0; node; i++, node= walker.nextNode() ) { if(node.nodeName == "article") node.className = 'classy' ; }
querySelectorAll
const elements = Array.from(document.body.querySelectorAll('article')) for(let el of elements){el.className = 'classy'}
NodeIterator
const walker = document.createNodeIterator( document.body, NodeFilter.SHOW_ELEMENT, ); for (let node = walker.nextNode(), i = 0; node; i++, node= walker.nextNode() ) { if(node.nodeName == "article") node.className = 'classy' ; }
