A practical functional library for JavaScript programmers emphasizing immutability and currying.
Ramda is a practical functional programming library for JavaScript that provides utilities for working with functions and data in a functional style. It solves the problem of writing clean, immutable, and side-effect free code by offering automatically curried functions and a data-last parameter order that facilitates function composition and pipeline creation.
JavaScript developers who want to adopt functional programming patterns, build complex data transformations through composition, or work with immutable data structures in their applications.
Developers choose Ramda for its focused functional design, automatic currying that simplifies partial application, and parameter ordering optimized for building functional pipelines, offering a more declarative alternative to imperative utility libraries.

Functions are automatically curried, enabling easy partial application and new function creation, as emphasized in the README's distinguishing features.
Parameters are arranged with data last, facilitating currying and seamless function composition for building pipelines, a core design choice.
Promotes pure functions and immutability, leading to predictable code, which is central to its functional programming philosophy.
Uses plain JavaScript objects and arrays, avoiding exotic constructs, making it feel familiar and practical, as stated in the philosophy section.
Focuses on reliable and quick implementations over functional purity dogma, ensuring efficiency in real-world use.
Achieving optimal bundle size requires specific configurations with Webpack plugins or Babel, as detailed in the Usage section, adding setup overhead.
The functional style, with currying and composition, can be challenging for developers used to imperative JavaScript, despite its practical aims.
TypeScript support relies on external typings (@types/ramda), and type inference for curried functions is often less intuitive than in native alternatives.
Ramda is an open-source alternative to the following products:
Underscore.js is the same as Underscore, a JavaScript library offering utility functions for common programming tasks in a functional style.
Lodash is a popular JavaScript utility library that provides consistent, modular functions for common programming tasks like array manipulation, object iteration, and function composition.
