Faster alternative to Ramda - Documentation

Rambda's advantages

Tree-shaking

Currenly Rambda is more tree-shakable than Ramda as you can see in this tree-shaking example.

Speed

Rambda is generally more performant than Ramda as the benchmarks can prove that.

You can clone this repo and run yarn run benchmark all to see for yourself.

dot notation for R.path

Standard usage of R.path is R.path(['a', 'b'], {a: {b: 1} }).

In Rambda you have the choice to use dot notation(which is arguably more readable):

R.path('a.b', {a: {b: 1} })

comma notation for R.pick and R.omit

Similar to dot notation, but the separator is comma(,) instead of dot(.).

R.pick('a,b', {a: 1 , b: 2, c: 3} })

// No space allowed between properties

Typescript included

Typescript definitions are included in the library, in comparison to Ramda, where you need to additionally install @types/ramda.

Rambda partially shadows Ramda's API, which means that you need to check Rambda's documentation to assure that all the methods you need are available.

Example use

const R = require('rambda')
const result = R.compose(
  R.map(x => x * 2),
  R.filter(x => x > 2)
)([1, 2, 3, 4])

// => [6, 8]

You can test this example in Rambda's REPL

Install

Use yarn add rambda for Webpack and Node.js usage
For UMD usage either use ./dist/rambda.umd.js or following CDN link:

https://cdnjs.cloudflare.com/ajax/libs/rambda/1.0.13/webVersion.js

Differences between Rambda and Ramda

Rambda's type detect async functions and unresolved Promises. The returned values are 'Async' and 'Promise'.
Rambda's path accepts dot notation('x.y' same as ['x','y'])
Rambda's pick and omit accept comma notation('x,y' same as ['x','y'])
Rambda's map and filter pass object key as second argument when mapping over objects.
Rambda's startsWith/endsWith work only with strings, instead with array and strings.
Rambda's flip works only for functions expecting two arguments.
Rambda's equals doesn't protect against circular structures as Ramda.equals does.
Rambda's partialCurry and includes are not part of Ramda API.

Try in REPL

zip

zip(a: K[], b: V[]): Array<KeyValuePair<K, V>>

It will return a new array containing tuples of equally positions items from both lists. The returned list will be truncated to match the length of the shortest supplied list.

R.zip([1, 2], ['A', 'B'])
// => [[1, 'A'], [2, 'B']]

// truncates to shortest list
R.zip([1, 2, 3, 4], ['A', 'B'])
// => [[1, 'A'], [2, 'B']]
