<h2>The JavaScript <i>this</i> Keyword</h2>
<p>In this example, <b>this</b> represents the <b>person</b> object.</p>
<p>Because the person object "owns" the fullName method.</p>
​
<p id="demo"></p>
​
<script>
// Create an object:
const person = {
  firstName: "John",
  lastName: "Doe",
  id: 5566,
  fullName : function() {
    return this.firstName + " " + this.lastName;
  }
};
​
// Display data from the object:
document.getElementById("demo").innerHTML = person.fullName();
</script>
