## What it is
Ramda is a practical functional programming utility library for JavaScript, offering curried, pure functions designed for building function pipelines without mutating data. It works with plain JavaScript objects and arrays and emphasizes immutability and side-effect-free design.

## Use cases
- write functional pipelines in javascript
- curry and compose functions
- transform data immutably
- avoid mutating objects and arrays
- build point-free style code
- replace lodash with a functional toolkit

## When to choose
- you want a pure functional style with automatic currying and data-last arguments
- you need immutable transformations of plain objects and arrays
- you prefer composing small functions into pipelines

## When to avoid
- your team is unfamiliar with functional programming concepts
- you need maximum raw performance over expressiveness
- you only need a few simple utilities that native JavaScript now covers

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: functional-programming, immutability, currying, point-free, utility-library, fantasy-land, algorithms, nodejs, deno, javascript
