JavaScript Object Methods

Last Updated : 30 Jul, 2025

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());

Output
STUDENT Martin 12th A
