In the world of JavaScript, the ‘prototype’ property is a fundamental concept that every developer should understand. It’s the key to creating efficient and reusable objects, and it’s the foundation for inheritance in the language.

In this article, we’ll dive deep into the ‘prototype’ property and explore how it can be used to enhance your JavaScript code.

Understanding Constructor Functions

Before we delve into the ‘prototype’ property, let’s first understand the concept of constructor functions. Constructor functions are a special type of function in JavaScript that are used to create objects. They are defined using the function keyword, and they typically have a capitalized name to distinguish them from regular functions. Here's an example of a simple constructor function:

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

const john = new Person('John', 30);
console.log(john.name); // Output: 'John'
console.log(john.age); // Output: 30
