<h2>The addEventListener() Method</h2>

<p>The difference between bubbling and capturing:</p>

<div id="myDiv">
  <p id="myP">Click this paragraph, I am Bubbling.</p>
</div><br>

<div id="myDiv2">
  <p id="myP2">Click this paragraph, I am Capturing.</p>
</div>

document.getElementById("myDiv").addEventListener("click", function() {
  myDisplay("You clicked the DIV element!");
}, false);

document.getElementById("myP2").addEventListener("click", function() {
  myDisplay("You clicked the P element!");
}, true);

document.getElementById("myDiv2").addEventListener("click", function() {
  myDisplay("You clicked the DIV element!");
}, true);

function myDisplay(text) {
  document.getElementById("demo").innerHTML += text + "<br>";
