fetch('https://jsonplaceholder.typicode.com/invalid-url')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => {
console.log(data);
})
.catch(error => {
console.error('There was a problem with the fetch operation:', error);
});
In this case, if the URL is invalid or there’s a network issue, the error is caught, and a message is logged.
