Pros
- Modern, modular date utility library with over 200 functions, allowing developers to import only what they need for optimal bundle size.
- Emphasizes immutability and pure functions, avoiding the mutation pitfalls common in older libraries like Moment.js.
- Lightweight, faster than Moment.js, and actively maintained with strong TypeScript support.
Cons
- Lacks some advanced date manipulation features compared to Moment.js, potentially requiring extra work for complex use cases.
- May throw exceptions on invalid dates rather than gracefully returning a placeholder, which can crash applications if not handled carefully.
- Learning curve due to the large number of functions; developers must understand which function to use for each operation.
