Adding a method to an object constructor is unlike adding a method to a normal object. We cannot add a method as it is the case with a normal object. To make a method in an object constructor it has to be added inside the object constructor.
Example
In the following example, the method is added inside the constructor, therefore, we have got a legitimate value.
<html>
<body>
<script>
function Business(name, property, age, designation) {
this.Name = name;
this.prop = property;
this.age = age;
this.designation = designation;
this.name = function() {
return this.Name
};
}
var person1 = new Business("Trump", "$28.05billion", "73", "President");
document.write(person1.name());
</script>
</body>
</html>Output
Trump
