• Three Ways to Convert JSON to TypeScript. Only One Is Deterministic.

  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 / 3 months ago

Next I will add the partial persistence code:. - Source: dev.to / over 1 year ago

  This may sound a bit general but we can't forget about well-tought code. If we are using a lot of external dependencies, we can check if there aren't many lighter alternatives. Example?
