const arrayToError = require('array-to-error');

arrayToError(messages [, constructor])

messages: Array of strings

The second argument is used as an error constructor.

const error = arrayToError(['foo', 'bar'], TypeError);
error.message; //=> 'foo\nbar'
error.reasons; //=> ['foo', 'bar']
error.constructor; //=> TypeError
