JavaScript, being a versatile and widely-used programming language, relies heavily on objects. Understanding object prototypes is crucial for any developer looking to write efficient and maintainable code.

In this article, we will delve into the fundamentals of object prototypes in JavaScript, providing clear explanations and practical code examples to help you grasp this essential concept.

What are Object Prototypes?

In JavaScript, every object has a prototype. A prototype is like a blueprint that defines the properties and methods that an object can inherit. When you create an object in JavaScript, it inherits properties and methods from its prototype. This inheritance mechanism allows for code reusability and helps in organizing and structuring your code effectively.

Creating Objects with Prototypes

Let’s start by creating a simple object using a constructor function and setting up its prototype:

function Person(name, age) {
  this.name = name;
  this.age = age;
}

Person.prototype.greet =…
