- Start game by generating a four-letter code you want the player to guess (generatedCode)

function generatedCode() {
for (let i = 0; i < 4; i++) {
const randomIndex = getRandomInt(0, letters.length);
solution += letters[randomIndex];
}

-- The player chooses 4 letters (playerCode)

-- They win if they guess the code before using up all of their turns
if (playerCode === generatedCode) {
console.log('You win!');
} else {
console.log('Keep trying');
}

-- The letters are checked to see:
1- if their code matches the generatedCode
2- if any of the letters are correct
(correct letter)
3- if they are also in the correct position
(correct position)
(Use 'loops', probably 'while' so can guess until generatedCode is true; or 'do while' if verifying playerCode and then running through rest of loop if incorrect...will see)

-- Alert the player of how many are the correct letter AND how many are in the correct position

-- The player loses if they use all of their turns and never guess the correct code

- Give 5 chances. Restart game when it's done.

-- Find a way to keep the players previous attempts and the results of those attempts on display
---save their inputs into an array
---show array on the screen

You need to return your "win" statement here, instead of just console logging here.

You only need one loop here.
