You query .logo into logo, but later code uses logo.before(...). If .logo is missing this will cause runtime errors. Consider appending to document.body in handlers or handle the logo === null case here so handlers don't rely on logo being non-null.


const promise1 = new Promise((resolve, reject) => {
if (logo) {
logo.addEventListener('click', () => {
resolve();
});
} else {
reject(new Error('no data'));
}
});

const promise2 = new Promise((resolve, reject) => {
setTimeout(reject, 3000);
});

const resolved = () => {
const div = document.createElement('div');

div.className = 'message';
div.textContent = 'Promise was resolved!';
document.body.append(div);
};

const rejected = () => {
const div = document.createElement('div');

div.className = 'message error-message';
div.textContent = 'Promise was rejected!';
document.body.append(div);
};

promise1.then(resolved).catch(rejected);
promise2.then(resolved).catch(rejected);
