Traversing the DOM
When we traverse the DOM, we’re essentially navigating through the DOM. We work with parent, child and sibling properties to apply our JavaScript to DOM elements.
We’ll be using a new example, as follows:
<!DOCTYPE html>
<html><head>
<title>Traversing the DOM</title>
</head><body>
<h1>Traversing the DOM</h1>
<p>Let's work with this example to <strong>MASTER</strong> the DOM!</p>
<h2>List of Items..</h2>
<ul>
<li>Pizza</li>
<li>Burgers</li>
<li>Doritos</li>
</ul>
</body><script>
const h1 = document.getElementsByTagName('h1')[0];
const p = document.getElementsByTagName('p')[0];
const ul = document.getElementsByTagName('ul')[0];
</script>
