A practical functional library for JavaScript programmers.

Last verified Sep 9, 2026 against ramda@0.32.0.

ramda publishes both a CommonJS entry and a native ESM entry (ESM added in 0.28.0). require("ramda") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "ramda" works alongside it.

## What to do

2. TypeScript: npm install -D @types/ramda
