const fetchData = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            reject('Error fetching data!');
        }, 1000);
    });
};

fetchData()
    .then(response => {
        console.log(response);
    })
    .catch(error => {
        console.error(error); // Output: Error fetching data!
    });
