Insert the HTML in the list
importance: 5
Write the code to insert <li>2</li><li>3</li> between two <li> here:
<ul id="ul"> <li id="one">1</li> <li id="two">4</li> </ul>When we need to insert a piece of HTML somewhere, insertAdjacentHTML is the best fit.
The solution:
one.insertAdjacentHTML('afterend', '<li>2</li><li>3</li>');
