Nested Destructuring The Nested Destructuring in JavaScript allows us to extract data from nested objects and arrays. An object (or array) can contain another object (or array) inside itself, known as a nested object (or array). Unpacking the nested objects or arrays is called nested destructuring. We can extract all or some data from the objects or arrays using […]

Object Destructuring The object destructuring assignments are JavaScript expressions that allow you to unpack and assign object properties into individual variables. The name of the individual variables can be the same as the object properties or different. The object destructuring is a very useful feature when you have an object with a lot of properties […]

Destructuring Assignment In JavaScript, the destructuring assignment is an expression that allows us to unpack the values from the arrays or objects and store them in individual variables. It is a technique to assign array values or object properties to the variables. The destructuring assignment syntax is introduced in ECMAScript 6 (ES6). Before ES6, developers were unpacking […]

Destructuring is a simple term we can use to extract values from array and properties from object. It is a JavaScript expression that help to unpack values from array or similarly properties from object into different variables. Let’s say you have a box that contain multiple items. Now, imagine someone asks you to take out […]

Polymorphism in JavaScript The polymorphism in JavaScript allows you to define multiple methods with the same name and different functionalities. Polymorphism is achieved by using method overloading and overriding. JavaScript does not support method overloading natively. Method overriding allows a subclass or child class to redefine a method of superclass or parent class. In this chapter, we will implement the […]

JavaScript has changed the website, application, and game development world and revolutionized the digital industry. JavaScript is mainly used with HTML and CSS to develop the application interface. However, nowadays, it is also used as a server-side programming language. In the world, according to stackoverflow survey 2023, around 63% of developers are using JavaScript. History […]

Inheritance in JavaScript The concept of inheritance in JavaScript allows the child class to inherit the properties and methods of the parent class. Inheritance is also a fundamental concept of object-oriented programming like encapsulation and polymorphism. Sometimes, you must add the properties and methods of the one class into another. For example, you have created a general class for the […]

What is Encapsulation? Encapsulation in JavaScript is a way to keep the related properties and methods under a single namespace by bundling them. It can be a function, a class or an object. In JavaScript, the encapsulation can be implemented using closures, classes and getters and setters. Encapsulation is a fundamental concept in Object-oriented programming […]

The ES5 Object methods in JavaScript are used to manipulate and protect the obejcts. ECMAScript 5 (ES5) is a significant revision of the language introduced in 2009. It has added many object methods to JavaScript. These methods provide us with efficient ways to iterate through object properties, manipulate values, and perform various operations on objects. Object manipulation […]

Native Prototypes The native prototypes in JavaScript are property of Object.prototype object. The prototypes are the mechanism by which the objects inherit features from one another. In JavaScript, each object contains the prototype property. The prototype of each object contains the methods and properties related to the object. So, it is also called the native prototype. However, you can update or add new methods and properties […]
