How do you prevent promises swallowing errors

How do you prevent promises from swallowing errors?

To prevent promises from swallowing errors, ensure that you handle rejections using .catch() or use try-catch with async-await syntax. Additionally, always return or throw errors explicitly.

Example:

Promise.resolve()
  .then(() => { throw new Error('Error occurred'); })
  .catch(error => console.error('Caught error:', error));

async function asyncFunction() {
  try {
    await Promise.reject('Error occurred');
  } catch (error) {
    console.error('Caught error:', error);
  }
}
asyncFunction();
