What does the new keyword do in JavaScript

Question

Can you tell me with proper code explanation that What does the new keyword do in JavaScript?

Answer 1

In JavaScript, the new keyword is used to create an instance of a constructor function or class. Here's how it works:

1. It creates a new, empty object.

2. It sets the prototype of the new object. The new object's __proto__ property is linked to the constructor function's prototype property, establishing the inheritance chain. This allows the new object to access properties and methods from the prototype.

3. It binds this to the new object. Inside the constructor function, this refers to the newly created object, enabling you to assign properties and methods to it.

4. It returns the new object. If the constructor function doesn't explicitly return a value, the new object is returned by default.
