<output id="result"></output>

const wrapper = document.createElement("div"); wrapper.appendChild(document.createTextNode("Part 1 ")); wrapper.appendChild(document.createTextNode("Part 2 ")); let node = wrapper.firstChild; let result = "Before normalization:\n"; while (node) { result += ` ${node.nodeName}: ${node.nodeValue}\n`; node = node.nextSibling; } wrapper.normalize(); node = wrapper.firstChild; result += "\n\nAfter normalization:\n"; while (node) { result += ` ${node.nodeName}: ${node.nodeValue}\n`; node = node.nextSibling; } const output = document.getElementById("result"); output.innerText = result;
