description: Fallback value for overflow option
info: |
sec-getoption step 3:
3. If _value_ is *undefined*, return _fallback_.
sec-temporal-totemporaloverflow step 1:
1. Return ? GetOption(_normalizedOptions_, *"overflow"*, « String », « *"constrain"*, *"reject"* », *"constrain"*).
sec-temporal-interprettemporaldatetimefields steps 2–3:
2. Let _temporalDate_ be ? DateFromFields(_calendar_, _fields_, _options_).
3. Let _overflow_ be ? ToTemporalOverflow(_options_).
sec-temporal-totemporalzoneddatetime steps 2–3:
2. If Type(_item_) is Object, then
...
j. Let _result_ be ? InterpretTemporalDateTimeFields(_calendar_, _fields_, _options_).
3. Else,
a. Perform ? ToTemporalOverflow(_options_).
sec-temporal.zoneddatetime.from steps 2–3:
2. If Type(_item_) is Object and _item_ has an [[InitializedTemporalZonedDateTime]] internal slot, then
a. Perform ? ToTemporalOverflow(_options_).
...
d. Return ...
3. Return ? ToTemporalZonedDateTime(_item_, _options_).
