JavaScript Object Methods

Last Updated : 26 Jul, 2023

Object Methods in JavaScript can be accessed by using functions. Functions in JavaScript are stored as property values. The objects can also be called without using brackets ().

In a method, 'this' refers to the owner object.
Additional information can also be added along with the object method.

Syntax:

objectName.methodName()

Properties: A function may be divided into different property values, which are then combined and returned together.
For Ex: The student function contains the properties:

name
class
section

Return Value: It returns methods/functions stored as object properties.

Example 1: This example uses function definition as the property value.

JavaScript

// Object creation
let student = {
    name: "Martin",
    class: "12th",
    section: "A",

    studentDetails: function () {
        return this.name + " " + this.class
            + " " + this.section + " ";
    }
};

// Display object data
console.log(student.studentDetails());

Output

Martin 12th A

Example 2: This example uses storing property values and accessing without bracket ().

JavaScript

// Object creation
let student = {
    name: "Martin",
    class: "12th",
    section: "A",

    studentDetails: function () {
        return this.name + " " + this.class
            + " " + this.section + " ";
    }
};

// Display object data
console.log(student.studentDetails);

Output

[Function: studentDetails]

Example 3: Using function definition as property value and accessing with additional details.

JavaScript

// Object creation
let student = {
    name: "Martin",
    class: "12th",
    section: "A",

    studentDetails: function () {
        return this.name + " " + this.class
            + " " + this.section + " ";
    }
};

// Display object data
console.log("STUDENT " + student.studentDetails());
