Tracking CodeFactor.io since Mar 2021.
Date strings. ISO 8601 timestamps like "2026-04-27T10:00:00Z" are string to the converter. If you're parsing them with date-fns or dayjs, you'll want to change those to Date in your final types. - Source: dev.to / 6 months ago
Dayjs - Fast 2kB alternative to Moment.js with the same modern API. - Source: dev.to / 9 months ago
I think the JS Date class should be avoided for anything related to DateTime. Instead, use one of the established libraries: Moment.js or Day.js. And in the near future, use the successor of Date, the new Temporal API. - Source: dev.to / 12 months ago
