Medieval Game Example

In the context of a Medieval game, Object.keys(), Object.values(), and Object.entries() can be used to access and display information about the game's characters, weapons, and items.

Here's an example of how Object.keys() can be used to display the properties of a character object:

let character = {
  name: "Sir Lancelot",
  level: 10,
  health: 100,
  weapon: "Excalibur"
};
console.log("Character Properties: " + Object.keys(character)); // Output: "Character Properties: name, level, health, weapon"

Here's an example of how Object.values() can be used to display the values of a weapon object:

let weapon = {
  name: "Dragon Slayer",
  damage: 50,
  type: "sword",
  rarity: "legendary"
};
console.log("Weapon values: " + Object.values(weapon)); // Output: "Weapon values: Dragon Slayer, 50, sword, legendary"

Here's an example of how Object.entries() can be used to display the key-value pairs of an inventory object:

let inventory = {
  potion: 5,
  gold: 200,
  scrollOfTeleportation: 2,
  amuletOfProtection: 1
};
console.log("Inventory: " + Object.entries(inventory)); 
// Output: "Inventory: [["potion",5], ["gold",200], ["scrollOfTeleportation",2], ["amuletOfProtection",1]]"

In a real game, these methods can be used in combination with loops and other array methods to display the information in a more organized way, for example, in a table or a list, or to filter out certain information, for example, displaying only items above a certain rarity.

It's worth mentioning that the order in which the properties are returned is the insertion order, so if you want them to be sorted in a certain way you need to use array methods like sort after using these methods.
