JavaScript Object Methods

0 0 1 minute read

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());
