Throws a RangeError if date arg is cast to an Infinity value
info: |
Intl.DateTimeFormat.prototype.formatRangeToParts ( startDate , endDate )
1. Let dtf be this value.
2. If Type(dtf) is not Object, throw a TypeError exception.
3. If dtf does not have an [[InitializedDateTimeFormat]] internal slot, throw a TypeError exception.
4. If startDate is undefined or endDate is undefined, throw a RangeError exception.
5. Let x be ? ToNumber(startDate).
6. Let y be ? ToNumber(endDate).
7. If x is greater than y, throw a RangeError exception.
8. Return ? FormatDateTimeRangeToParts(dtf, x, y).
FormatDateTimeRangeToParts ( dateTimeFormat, x, y )
1. Let parts be ? PartitionDateTimeRangePattern(dateTimeFormat, x, y).
PartitionDateTimeRangePattern ( dateTimeFormat, x, y )
1. Let x be TimeClip(x).
2. If x is NaN, throw a RangeError exception.
3. Let y be TimeClip(y).
4. If y is NaN, throw a RangeError exception.
TimeClip ( time )
1. If time is not finite, return NaN.
