esid: sec-temporal.calendar.prototype.mergefields
description: Both string and symbol keys from the arguments are merged
info: |
1. Let calendar be the this value.
2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]).
3. Assert: calendar.[[Identifier]] is "iso8601".
4. Set fields to ? ToObject(fields).
5. Set additionalFields to ? ToObject(additionalFields).
6. Return ? DefaultMergeFields(fields, additionalFields).
