This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Case
HOW- Goal
- Configure Luxon error handling and distinguish silent invalid object propagation from immediate exceptions using Settings.throwOnInvalid
- Packages
- Symbols
-
- DateTime.fromISO
- DateTime.fromObject
- Settings.throwOnInvalid
- Interval.fromDateTimes
- Environment
- node
- Created
- 2026-08-16T18:38:35Z
Contract
- DateTime.fromISO with an unparsable string or impossible calendar date does not throw and does not roll over, returning an invalid DateTime object with isValid false and toISO null
- Operations and arithmetic on an invalid DateTime propagate isValid false without throwing, returning NaN for toMillis and null for toISODate
- DateTime.fromObject with month 0 is treated as out of range and invalid rather than wrapping to January or December
- Setting Settings.throwOnInvalid to true switches Luxon from silent invalid object propagation to immediately throwing an Error on invalid parsing, units, or timezones
- Interval.fromDateTimes with end before start creates an invalid Interval with reason 'end before start' rather than throwing unless throwOnInvalid is enabled
