Remeda is designed to be a minimalistic and lightweight library, focusing on providing essential utility functions. Underscore, on the other hand, has a larger code base and includes a broader range of functionalities. If size is a concern, Remeda may be a better choice.
Remeda is modular and each function is a separate module, allowing developers to import only the specific functions they need. Underscore, on the other hand, is a single monolithic library, requiring you to include the entire library even if you only need a few functions. This can result in unnecessary overhead and larger bundle sizes.
Underscore provides a rich set of utility functions that cover many common use cases. It includes functions for collection manipulation, functional programming, object manipulation, and more. Remeda also provides similar utility functions, but the range of functionalities may be more limited compared to Underscore.
