| sec-getoption step 10: |
| 10. If _values_ is not *undefined* and _values_ does not contain an element equal to _value_, throw a *RangeError* exception. |
| sec-temporal-totemporaloverflow step 1: |
| 1. Return ? GetOption(_normalizedOptions_, *"overflow"*, « String », « *"constrain"*, *"reject"* », *"constrain"*). |
| sec-temporal.calendar.prototype.dateadd step 7: |
| 7. Let _overflow_ be ? ToTemporalOverflow(_options_). |
| sec-temporal-adddatetime step 4: |
| 4. Let _addedDate_ be ? CalendarDateAdd(_calendar_, _datePart_, _dateDuration_, _options_). |
| sec-temporal.plaindatetime.prototype.subtract step 5: |
| 5. Let _result_ be ?
