Another experiment we did in class -
<html>
<body id="body">
<h2>Todo 1</h2>
<h2>Todo 2</h2>
<h2>Todo 3</h2>
<button onclick="deleteRandomTodo()">Delete todo!</button>
</body>
<script>
function deleteRandomTodo() {
const element = document.querySelector("h2");
const parentElement = element.parentNode;
parentElement.removeChild(element);
}
</script>
