Looks like...
JavaScript
let secretNumber = Math.trunc(Math.random() * 20) + 1;
let score = 20;
let highscore = 0;
document.querySelector('.check').addEventListener('click', function () {
const guess = Number(document.querySelector('.guess').value);
// console.log(typeof guess);
// When there is no input
if (!guess) {
document.querySelector('.message').textContent = 'â›” No Number!';
// Win player wins
} else if (guess === secretNumber) {
document.querySelector('.message').textContent = '🎉 Correct Number!';
document.querySelector('.number').textContent = secretNumber;
document.querySelector('body').style.backgroundColor = '#60b347';
document.querySelector('.number').style.width = '30rem';
if (score > highscore) {
highscore = score;
document.querySelector('.highscore').textContent = highscore;
}
// When guess is too high
} else if (guess > secretNumber) {
if (score > 1) {
document.querySelector('.message').textContent = '📈 Too high!';
score--;
document.querySelector('.score').textContent = score;
} else {
document.querySelector('.message').textContent = '💥 You lost the game!';
document.querySelector('.score').textContent = 0;
}
// When guess is too low
} else if (guess < secretNumber) {
if (score > 1) {
document.querySelector('.message').textContent = '📉 Too low!';
score--;
document.querySelector('.score').textContent = score;
} else {
document.querySelector('.message').textContent = '💥 You lost the game!';
document.querySelector('.score').textContent = 0;
}
}
});
document.querySelector('.again').addEventListener('click', function () {
secretNumber = Math.trunc(Math.random() * 20) + 1;
score = 20;
document.querySelector('.message').textContent = 'Start guessing...';
document.querySelector('.score').textContent = score;
document.querySelector('.number').textContent = '?';
document.querySelector('.guess').value = '';
document.querySelector('body').style.backgroundColor = '#222';
document.querySelector('.number').style.width = '15rem';
});
