                <ol>
                  <li>Create some objects</li>

                  <li>Take heap snapshot</li>

                  <li>Compare memory usage</li>
                </ol>

                <p>
                  <button class="button--primary" onclick="createObjects123()">Create objects</button>
                </p>
