The JavaScript apply() Method
The apply() method is similar to the call() method (previous chapter).
In this example the fullName method of person is applied on person1:
<script>
var person = {
fullName: function() {
return this.firstName + " " + this.lastName;
}
}
var person1 = {
firstName:"John",
lastName: "Doe"
}
var x = person.fullName.apply(person1);
document.getElementById("demo").innerHTML = x;
</script>
