How can you handle a promise rejection in an asynchronous function?

You can use try...catch.

async function processData() {
  try {
    const result = await fetchData(); // fetchData() may return a promise that is rejected
    console.log('Data successfully received:', result);
  } catch (error) {
    console.error('Error fetching data:', error);
    // Additional error handling actions can be performed here
    // For example, showing a message to the user or logging
  }
}

// Alternative method with .catch() (less common in async/await)
async function processDataAlt() {
  await fetchData()
    .then(result => {
      console.log('Data successfully received:', result);
    })
    .catch(error => {
      console.error('Error fetching data:', error);
    });
}

Using try...catch is more preferred and idiomatic for async/await. It allows centralizing error handling in one block and appears more synchronous.
