Script Preparation code:
 
// Needs var hoisting, can't use let or const declarations!
var htmlTemplate = document.querySelector("template");
var myHTML = `<div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div><div></div>`;
htmlTemplate.innerHTML = myHTML;
var globalTemplate = document.createElement("template");
globalTemplate.innerHTML = myHTML;
var clonedTemplate = globalTemplate.content.cloneNode(true);
Tests:

  • T1 - set innerHTML

     
    document.querySelector("#T1").innerHTML = myHTML;

  • T2 - clone template - appendChild

     
    document.querySelector("#T2").appendChild(globalTemplate.content.cloneNode(true));

  • T3 - clone Template - append

     
    document.querySelector("#T3").append(globalTemplate.content.cloneNode(true));

  • T4 - clone HTML Template

     
    document.querySelector("#T4").append(htmlTemplate.content.cloneNode(true));
