Clide side templating vs Javascript templating

createElement.js

((title,bodyText) => {
  var div = document.createElement("div");
  div.className = "entry";
  
  var h1 = document.createElement("h1");
  var textH1 = document.createTextNode(title);
  h1.appendChild(textH1);

  var innerDiv = document.createElement("div");
  innerDiv.className = "body";
  var innerDivText = document.createTextNode(bodyText);
  innerDiv.appendChild(innerDivText);

  div.appendChild(h1);
  div.appendChild(innerDiv);
  
  document.body.appendChild(div);
  
})("Medium story","This is my first post!");
