What are object prototypes in JavaScript?

Asked on Jul 23, 2025

Answer

Object prototypes in JavaScript are a mechanism by which objects inherit properties and methods from other objects. This allows for shared functionality across instances.

// Create a prototype object
        const animal = {
            speak() {
                console.log("Animal speaks");
            }
        };

        // Create a new object that inherits from the animal prototype
        const dog = Object.create(animal);
        dog.speak(); // Output: Animal speaks

Additional Comment:

The "animal" object acts as a prototype for the "dog" object.
"dog" inherits the "speak" method from "animal".
"Object.create" is used to create a new object with a specified prototype.
Prototypes allow for efficient method sharing across multiple objects.
