Lazy.js is a functional utility library for JavaScript that provides lazy evaluation and immutable data structures. It offers a wide range of methods for working with arrays, objects, and sequences in a functional programming style. Lazy.js allows developers to create efficient data processing pipelines by chaining operations and delaying execution until necessary.
Remeda is a functional programming utility library for JavaScript that provides a set of immutable and efficient functions for working with arrays, objects, and other data structures. It offers a wide range of utility functions like map, filter, reduce, and more, allowing developers to perform common operations in a functional and declarative way.
Lazy.js and Remeda are both popular npm packages, but Remeda has gained more popularity in recent years. It has a growing community and is actively maintained.
Size
Lazy.js is a lightweight library with a small footprint, making it suitable for projects where size is a concern. Remeda is also relatively small, but it offers a more extensive set of utility functions.
Functionality
Lazy.js is primarily focused on providing lazy evaluation and functional programming capabilities. It offers a range of methods for working with collections and provides a fluent API. Remeda, on the other hand, is a utility library that provides a wide range of functions for common data manipulation tasks, including array, object, and string operations.
Performance
Both Lazy.js and Remeda are designed to be performant, but Lazy.js is specifically optimized for lazy evaluation, which can provide performance benefits in certain scenarios. Remeda also aims for good performance and provides optimized implementations for its utility functions.
Developer Experience
Lazy.js has a clean and intuitive API that is easy to understand and use. It provides comprehensive documentation and examples. Remeda also has a well-documented API and offers TypeScript support, which can enhance the developer experience, especially for projects using TypeScript.
Maintenance
Both libraries are actively maintained, but Remeda has a more recent release history and a larger contributor base. This indicates that Remeda is likely to receive more frequent updates and bug fixes.
