+INFO: Object Prototypes
+JavaScript is prototype-based, meaning every object in JavaScript has a hidden [[prototype]] (commonly accessed via .prototype or __proto__).
+*/
+
+/*
+INFO: What is prototype ?
+A prototype is just another object that your object inherits properties and methods from.

+admin.__proto__ = user;
+
+console.log(admin.name); // "Rafay"
+admin.greet(); // Hello, Rafay
+
+/*
+INFO: Object.getPrototypeOf() and Object.setPrototypeOf()
+you can also get/set protypes programmatically:
+*/
+Object.getPrototypeOf(admin); // user
+Object.setPrototypeOf(admin, {}); // change prototype
+
+/*
+INFO: Object.prototype
+Every object eventually links to Object.prototype, unless you create it with Object.create(null).
+*/
+
+/*
+INFO: Prototype Chain
+When you access a property:
+1. Js looks at the object itself.
+2. If not found, it looks in its prototype.
+3. Then the prototype's prototype... and so on, until it hits null.
+This is called Prototype Chain.
