Line 4 uses comma to execute stuff and then return last expression, which is e - so the div https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comma_Operator @mzeeshan It's more readable in this form:

  const e = document.createElement("div");
  e.innerHTML = ["Hello", "webpack"].join(" ");
  return e;

  const e = document.createElement("div");
  e.innerHTML = ["Hello", "webpack"].join(" ");
  return e;
