Using the getElementById method

In HTML, you can assign an element an ID and then retrieve it back in JavaScript for manipulation. Here's how:

<div id="myID">My Content Here</div><script>const myID = document.getElementById('myID'); // myID now contains reference to the div above</script>

Once you have that, you can access the properties of this object, which in turn actually modifies the element on the screen accordingly.
