FPS Example

Here's an example of using the every() method in the context of a first-person shooter game:

Let's say we have an array of objects representing the players in a multiplayer game, with each object containing properties like the player's username, level, and rank. Here's an example of such an array:

const players = [
  { username: "player1", level: 30, rank: "Gold" },
  { username: "player2", level: 20, rank: "Silver" },
  { username: "player3", level: 40, rank: "Platinum" },
  { username: "player4", level: 50, rank: "Diamond" }
];

Now, let's say we want to check whether all the players in the game have a rank of "Gold" or higher. We can use the every() method to do this by calling every() on the players array and passing a function that checks the rank property of each object. Here's how we could do this:

const allGoldOrHigher = players.every(player => player.rank === "Gold" || player.rank === "Platinum" || player.rank === "Diamond");

console.log(allGoldOrHigher); // Output: false

In this example, every() returns false because not all players have a rank of "Gold" or higher. If we wanted to check whether all players have a level of 30 or higher, we could modify the callback function like this:

const allLevel30OrHigher = players.every(player => player.level >= 30);

console.log(allLevel30OrHigher); // Output: true

In this case, every() returns true because all players have a level of 30 or higher.
