What is the correct term for a JSON object with methods?

Question

If I have the following code:

var person = {
    firstName: "John",
    lastName : "Doe",
    id       : 5566,
    fullName : function() {
       return this.firstName + " " + this.lastName;
    }
};

What is it called? Is it just a JSON object, even though it has a function binding? In the example I gave, could I call fullName a method?

Answer 1

You can find the difference in JSON & Object literal here .

• person is an object literal.

• Properties ( firstName, lastName, id ) is like a noun which refers the person details.

• Method ( fullName ) is like a verb that describes an action.

 var person = { firstName: "John", lastName : "Doe", id : 5566, fullName : function() { return this.firstName + " " + this.lastName; } }; console.log("FirstName :", person.firstName); console.log("Full Name :", person.fullName()); 

Here, person is an object. It has a property person.firstName , person.lastName , person.id and method person.fullName() that return full name of the person which include the person firstName & lastName property.
