How to Define an Empty Object in JavaScript?

In JavaScript, you can define an empty object by using either object literal notation or the Object() constructor.

Here’s how you can define an empty object using object literal notation:

const myObject = {};

In this example, we define a new object called myObject using object literal notation. This creates an empty object with no properties or methods.

Here’s how you can define an empty object using the Object() constructor:

const myObject = new Object();

In this example, we define a new object called myObject using the Object() constructor. This also creates an empty object with no properties or methods.

Both of these methods create an empty object, but object literal notation is more commonly used in JavaScript because it is more concise and easier to read. However, the Object() constructor can be useful if you need to set properties or methods on the object during construction. For example:

const myObject = new Object();
myObject.name = 'John';
myObject.age = 30;

In this example, we define an empty object using the Object() constructor, and then set two properties on the object using dot notation. This creates an object with two properties, name and age, which can be accessed and modified like any other object property.
