<h1>The createEvent() Method</h1>
<p>The createEvent() method allows you to simulate any event.</p>
<p>In this example, the red div will get a new star every time you mouse over it:</p>
<div onmouseover="this.innerHTML += '*';" id="myDiv">*</div>
<br>
<button onclick="myFunction(event)">Simulate Mouse Over</button>
