Rhythm Game Example

Here's an example of how arrow functions can be used to handle button presses:

document.getElementById("leftButton").addEventListener("click", () => {
  player.moveLeft();
});
document.getElementById("rightButton").addEventListener("click", () => {
  player.moveRight();
});

In this example, arrow functions are passed as callbacks to the addEventListener method. When the left button or the right button is clicked, the corresponding arrow function is invoked, which calls the moveLeft() or moveRight() method on the player object.

Another example, a function that handle the score and accuracy of the player

let score = 0;
let accuracy = 0;
let noteChecker = (note) => {
  if(note.status === "hit") {
    score += 100;
    accuracy += 1;
  } else {
    score -= 50;
  }
  updateScore();
  updateAccuracy();
}

In this example, the arrow function noteChecker is used to check if a note is hit or missed by the player, and updates the score and accuracy accordingly. The updateScore() and updateAccuracy() are also functions that would update the score and accuracy on the screen.
