+## API
+
+### AggregateError(errors)
+
+Returns an `Error` that is also an [`Iterable`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators#Iterables) for the individual errors.
+
+#### errors
+
+Type: `Array<Error|Object|string>`
+
+If a string, a new `Error` is created with the string as the error message.<br>
+If a non-Error object, a new `Error` is created with all properties from the object copied over.
