Prototypes and Inheritance

Expert-Level Explanation

Prototypes are the mechanism by which JavaScript objects inherit features from one another. In JavaScript, every object has a prototype, and objects can inherit properties and methods from their prototype.

Creative Explanation

Consider prototypes in JavaScript as family traits passed down through generations. Just like children inherit genes from their parents, an object can inherit properties and methods from its prototype.

Practical Explanation with Code

function Robot(name) {
    this.name = name;
}

Robot.prototype.performTask = function(task) {
    console.log(this.name + " is performing: " + task);
};

let robot1 = new Robot("Robo1");
robot1.performTask("painting"); // Output: Robo1 is performing: painting

Real-world Example

Prototypes are like inherited family recipes. Each new generation (object) can use and add to these recipes, creating a shared family culinary tradition.
