AggregateError — also an Error

📖 Usage Example

Promise.any([Promise.reject(new Error('e1')), Promise.reject(new Error('e2'))])
  .catch(e => e instanceof AggregateError)  // → true

Promise.any() rejects with an AggregateError when all promises reject.

AggregateError extends Error

AggregateError extends the built-in Error class.

Challenge: Verify that an AggregateError is also an instance of Error.
