Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Limited timezone support
date-fns does not natively handle timezones, requiring additional libraries like date-fns-tz for comprehensive timezone functionality.
- 02
No built-in i18n support
Localization and internationalization require external libraries or manual implementation, which can complicate projects with global reach.
- 03
Documentation lacks advanced use cases
The documentation focuses on basic usage patterns and examples but falls short in providing detailed guidance for complex scenarios.
What it does well
Modular and lightweight
Simple, consistent API
No dependencies
