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.

ramda

v0.30.1(18 days ago)

This package is actively maintained.Types definitions are provided via a separate npm package: @types/ramdaNumber of direct dependencies: 0Monthly npm downloads

Ramda is a functional programming library for JavaScript that emphasizes immutability and side-effect-free functions. It provides a set of utility functions that enable functional programming paradigms like currying, composition, and partial application. Ramda's functions are designed to be easily composable, allowing developers to create complex transformations by chaining simple functions together.

Fight!

Popularity

Ramda is more popular and widely used compared to Lazy.js. Ramda has a larger community and a more active development ecosystem.

Size

Lazy.js is a lightweight library with a small footprint, making it suitable for projects where size is a concern. Ramda, on the other hand, has a larger codebase and may add more overhead to your project.

Functional Programming

Both Lazy.js and Ramda are functional programming libraries, but they have different focuses. Lazy.js provides lazy evaluation and sequence manipulation, allowing for efficient processing of large data sets. Ramda, on the other hand, provides a wide range of utility functions for functional programming, immutability, and data transformation.

API Design

Lazy.js has a simple and intuitive API that is easy to learn and use. It provides a chainable API for method chaining and supports method composition. Ramda also has a well-designed API, but it follows a more functional programming style with currying and data-last argument order.

Browser Support

Lazy.js has broader browser support and can work in older browsers. Ramda, on the other hand, may require polyfills or transpilation to work in older environments.

Documentation

Both libraries have good documentation, but Ramda's documentation is more extensive and provides detailed examples and explanations for each function. Lazy.js documentation is also comprehensive but may not have as many community-contributed examples.
