JavaScript Object with Methods

by Abdul Rawoof A R Updated: Mar 2, 2023

Guide Kit

In JavaScript, objects are collections of key/value pairs, and the values can consist of properties and methods and may contain all other JavaScript data types, like strings, numbers, and Booleans.

Objects have properties and methods. Object Methods can be accessed using functions in JavaScript, which are stored as property values in JavaScript. The objects can also be called without using brackets(), and in a method, 'this' refers to the owner object, and we need to have a class before we can create an object. A method is a procedure associated with a class and defines the behavior of the objects created from the class. To print methods of objects in JavaScript, stringify() method is used. The JSON.stringify() method allows us to take a JavaScript object or array and create a JSON string. We cannot call a method without an object to access the methods in JavaScript.

Here is an example of a JavaScript object with methods:

JavaScriptLines of Code : 18License : Strong Copyleft (CC BY-SA 4.0)

function Bar() {
    return function() {
        return this;
    }.bind(this);
}

Bar.prototype.start = function (fn) { fn(); return this; };
Bar.prototype.end = function (fn) { fn(); return this; };

var foo = new Bar();

foo()
    .start(function(param) {
        console.log("start");
    })
    .end(function(param) {
        console.log("end");
    })

Instructions

Follow the steps carefully to get the output easily.

Install JavaScript ES6 code snippet and Code Runner from Extension on your IDE(We use Visual Studio Code).
Copy the snippet using the 'copy' and create one new file filename.js(eg.test.js) then paste the code in that JavaScript file.
Save the file and run the file using run button to generate the output.

I hope you found this useful.

I found this code snippet by searching for 'how to implement javascript object with methods'in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

The solution is created and tested in Visual Studio Code 1.74.1.
JavaScript ES6 Code Snippet version v1.8.0.
Code Runner version v0.11.8.

Using this solution, we are able to implement javascript object with methods with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement javascript object with methods.
