![]() ![]() To run the test suite from the console, you need to have mocha installed: npm install -g mocha Speakers, lambs are baby sheep, ewes are female sheep, and rams are male It could as easily have been eweda, but then we would beįorced to say eweda lamb!, and no one wants that. DocumentationĪlso available is our Cookbook of functions built from Ramda that you may find useful. Install individual functions with bit, npm and yarn without installing the whole library. This requires having Node/io.js installed and ramda's dependencies installed (just use npm install before running partial build). For example if you're using R.compose, R.reduce, and R.filter you can create a partial build with: npm run -silent partial-build compose reduce filter > dist/ Ramda's build system supports this with command line flags. It is possible to build Ramda with a subset of the functionality to reduce its file size. Npm run build creates es, src directories and updates both dist/ramda.js and dist/ Partial Builds In order to access to the ES6 module in browsers, one has to provide the content of the es directory (see below for the build instructions) and use import * as R from './node_modules/ramda/es/index.js' Build Or better yet, import only the required functions via import from 'ramda' ![]() So instead of import R from 'ramda', one has to use import * as R from 'ramda' Ramda versions > 0.25 don't have a default export. Or you can inject ramda into virtually any unsuspecting website using the bookmarklet. These script tags add the variable R on the browser's global scope. (note that using latest is taking a significant risk that ramda API changes could break your code.) ![]() Or one of the below links from jsDelivr: To use directly in Deno: import * as R from using Nest.land: import * as R from use directly in the browser: Then in the console: const R = require('ramda') Implementation wins over any notions of functional purity. Last but not least, Ramda strives for performance. We sacrifice a great deal of implementation elegance for even a slightly We aim for an implementation both clean and elegant, but the API is king. While Ramda does not enforce this, itĮnables such style to be as frictionless as possible. Native features of JavaScript, such as functions as objectsįunctional programming is in good part about immutable objects and Our basic data structures are plain JavaScript objects, and our Lists, we're not porting over all of the Clojure functions. ![]() Lambda expressions in strings, we're not borrowing consed Using Ramda should feel much like just using JavaScript. Hey Underscore, You're Doing It Wrong! by Brian Lonsdorf.Ramda is designed to support this style of coding. The last two points together make it very easy to build functions as sequences of simpler functions, each of which transforms the data and passes it along to the next. To be operated on is generally supplied last. The parameters to Ramda functions are arranged to make it convenient for currying. This allows you to easily build up new functionsįrom old ones simply by not supplying the final parameters. Ramda functions are automatically curried. This can help you get the job done with simple, Immutability and side-effect free functionsĪre at the heart of its design philosophy. Ramda emphasizes a purer functional style. The primary distinguishing features of Ramda are: We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. There are already several excellent libraries with a functional flavor. A practical functional library for JavaScript programmers. ![]()
