Understanding Objects in JavaScript

JavaScript objects play a significant role in structuring data, and understanding how to use them is an essential part of modern JavaScript development. In this guide, we'll dive into the usage, properties, and methods of objects.

What are JavaScript Objects?

An object in JavaScript is a standalone entity, with properties and type. It is a collection of related data and/or functionality which usually consists of several variables and functions — which are called properties and methods when they are inside objects.

Creating Objects

Objects in JavaScript can be created using the object literal syntax, or by using the new keyword with a constructor function. Let's look at examples for each method.

Object Properties

Properties are the values associated with a JavaScript object. A JavaScript object is a collection of unordered properties. Properties can usually be changed, added, and deleted, but some are read only.

Object Methods

Methods are actions that can be performed on objects. Object properties can be both primitive values, other objects, and functions. An object method is an object property containing a function definition.
