/*
Object oriented design is commonly used in video games. For this part of the assignment
you will be implementing several classes with their correct inheritance heirarchy.
In this file you will be creating three classes:
GameObject
createdAt
dimensions
destroy() // prototype method -> returns the string 'Game object was removed from the game.'*/

Inheritance chain: Humanoid -> NPC -> GameObject
Instances of Humanoid should have all of the same properties as NPC and GameObject.
Instances of NPC should have all of the same properties as GameObject.
Example:
const hamsterHuey = new Humanoid({
createdAt: new Date(),
dimensions: {
length: 2,
width: 1,
height: 1,
},
hp: 5,
name: 'Hamster Huey',
faction: 'Gooey Kablooie',
weapons: [

],
language: 'Hamsterish',
});
hamsterHuey.greet(); // returns 'Hamster Huey offers a greeting in Hamsterish'
hamsterHuey.takeDamage(); // returns 'Hamster Huey took damage.'
hamsterHuey.destroy(); // returns 'Game object was removed from the game.'
