Prototypal Inheritance:
Prototypal Inheritance is a feature in JavaScript that allows an object to inherit properties and methods from another object. It is one of the core concepts behind JavaScript's object system, and it works differently from classical inheritance found in languages like Java or C++.
How it Works:
In JavaScript, every object has a hidden internal property called [[Prototype]] (accessible via proto or set using Object.setPrototypeOf() or Object.create()), which refers to another object. That other object is its prototype.
When you try to access a property or method on an object, JavaScript:
<ol>
<li>First looks for the property on the object itself.</li>
<li>If not found, it looks at the object’s prototype (proto).</li>
<li>If still not found, it continues up the prototype chain until it finds the property or reaches null.</li>
</ol>
Example:
const grandParent = {
sayGrandParent() {
console.log("I am the Grandparent");
}
};
const parent = Object.create(grandParent);
parent.sayParent = function () {
console.log("I am the Parent");
};
const child = Object.create(parent);
child.sayChild = function () {
console.log("I am the Child");
};
child.sayChild(); // I am the Child --&gt; found in child
child.sayParent(); // I am the Parent --&gt; inherited from parent
child.sayGrandParent(); // I am the Grandparent --&gt; inherited from grandParent

It is hard to explain something clearly. I'd suggest you take a top-down approach for this kind of abstract concept. for example. 1. generally what it…
