5,492 PointsIt might seem daunting with all the code but the solution is a quick one liner :).
The “div” variable contains the headline that we’ll want to add the link after. We can see this with the div.appendChild(h2).
The link is associated with the “link” variable. It was used earlier to append the p variable to it. We can reuse the link variable but this time have it append to a node instead of it being the node itself.
div.appendChild(link) should do it. :)
