One of many massive themes of the net lately is concurrency, which ends up in carrying out duties asynchronously. In doing so, the potential for a number of errors can happen. As an alternative of offering a generic error, optimally you’d present a wealth of error info. The

const error = new AggregateError([ new Error('ERROR_11112'), new TypeError('First name must be a string'), new RangeError('Transaction value must be at least 1'), new URIError('User profile link must be https'), ], 'Transaction can't be processed')
AggregateError will get you the next info:
error instanceof AggregateError // true error.identify // 'AggregateError' error.message // 'Transaction can't be processed' error.errors // The array of errors
