In this article, you will learn about the JavaScript constructor functions with the help of examples. Let’s get right into it.

What is a Constructor Function?

In JavaScript, a constructor function is used to create new objects. It defines properties and behaviors that will belong to the new object. Think of it as a blueprint for the creation of new objects.

Here is an example of a constructor:

function Car() {
  this.name = "Ford";
  this.color = "blue";
  this.speed = 260;
}

This constructor defines a **C**ar object with some properties(name-color-speed).

Constructors follow a few conventions:

• Constructors are defined with a capitalized name to distinguish them from other functions that are not constructors.
• Constructors use the keyword this to set properties of the object they will create. Inside the constructor, this refers to the new object it will create.
• Constructors define properties and behaviors instead of returning a value as other functions might.
