Benchmark: Different ways (template, vanilla js, innerHTML) to create DOM nodes

Script Preparation code:

var simpleTemplate = document.createElement("template");
simpleTemplate.innerHTML = `<span class="simple"></span>`;
  
var complexTemplate = document.createElement("template");
  complexTemplate.innerHTML = 
  `<span class="complex">
      <span class="simple-1"></span>
      <span class="simple-2">
          <span class="simple-2-1"></span>
      </span>
      <span class="simple-3">
          <span class="simple-3-1"></span>
      </span>
      <span class="simple-4"></span>
  </span>`;

Tests:

complex template
let el = document.createElement("div"); let content = complexTemplate.content.cloneNode(true); el.appendChild(content);
complex javascript
let el = document.createElement("span"); el.classList.add("complex"); let span1 = document.createElement("span"); span1.classList.add("simple-1"); let span2 = document.createElement("span"); span2.classList.add("simple-2"); let span21 = document.createElement("span"); span21.classList.add("simple-2-1"); span2.appendChild(span21); let span3 = document.createElement("span"); span3.classList.add("simple-3"); let span31 = document.createElement("span"); span31.classList.add("simple-31"); span3.appendChild(span31); let span4 = document.createElement("span"); span4.classList.add("simple-4"); el.append(span1, span2, span3, span4);
complex innerhtml
let el = document.createElement("div"); el.innerHTML = ` `;
