Party game example

Here is an example of a function that returns a promise in the context of a party computer game:

function startNewGame(gameType) {
  return new Promise((resolve, reject) => {
    if (gameType === 'trivia') {
      console.log('Starting a new trivia game...');
      // simulate game setup with a 2 second delay
      setTimeout(() => {
        resolve();
      }, 2000);
    } else if (gameType === 'charades') {
      console.log('Starting a new charades game...');
      // simulate game setup with a 2 second delay
      setTimeout(() => {
        resolve();
      }, 2000);
    } else {
      reject(new Error('Invalid game type'));
    }
  });
}

startNewGame('trivia')
  .then(() => {
    console.log('Trivia game started successfully!');
  })
  .catch((error) => {
    console.log(error.message);
  });

This function takes in a gameType argument, which can be either 'trivia' or 'charades'. If the gameType is valid, the function will "start" the game by simulating a 2 second delay (using setTimeout) to represent the setup process. If the gameType is invalid, the function will reject the promise with an error.

The function returns a promise that is resolved or rejected based on the outcome of the game setup process. The calling code can use the then and catch methods to handle the resolved or rejected promise, respectively.

I hope this helps! Let me know if you have any questions.
