esid: sec-temporal.plaindate.compare
description: Fast path for converting Temporal.PlainDateTime to Temporal.PlainDate by reading internal slots
info: |
sec-temporal.plaindate.compare steps 1–2:
1. Set _one_ to ? ToTemporalDate(_one_).
2. Set _two_ to ? ToTemporalDate(_two_).
sec-temporal-totemporaldate step 2.b:
b. If _item_ has an [[InitializedTemporalDateTime]] internal slot, then
i. Return ! CreateTemporalDate(_item_.[[ISOYear]], _item_.[[ISOMonth]], _item_.[[ISODay]], _item_.[[Calendar]]).
