Prototypal inheritance is a fundamental concept in JavaScript, allowing objects to inherit properties and methods from other objects.

In this guide, we’ll uncover the best practices for prototypal inheritance, providing practical advice and up-to-date code examples to help you write cleaner, more efficient, and maintainable JavaScript code.

Understanding Prototypal Inheritance

Prototypal inheritance forms the basis of object-oriented programming in JavaScript. Objects inherit properties and methods from their prototypes through a chain of prototypes, known as the prototype chain.

const parent = {
  greet: function() {
    console.log('Hello from parent');
  }
};

const child = Object.create(parent);
child.greet(); // Output: Hello from parent

In this example, child inherits the greet() method from its prototype (parent), demonstrating prototypal inheritance in action.
