Discussion on: innerHTML Vs. textContent: The subtle difference.

      let a = document.createElement("em");
      let b = document.createElement("strong");
      let c = document.createElement("span");

          a.textContent = "I ";
          b.textContent = "love ";
          c.textContent = "javascript";
          c.style.cssText = "color: red;";

             let d = document.querySelector("#output");

                      d.appendChild(a);
                       d.appendChild(b);
                        d.appendChild(c);
