Rambda

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/1.2.1/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.

uniqWith

uniqWith(fn: Function, arr: T[]): T[]

It returns a new array containing only one copy of each element in arr according to boolean returning function fn.

const arr = [
  {id: 0, title:'foo'},
  {id: 1, title:'bar'},
  {id: 2, title:'baz'},
  {id: 3, title:'foo'},
  {id: 4, title:'bar'},
]

const expectedResult = [
  {id: 0, title:'foo'},
  {id: 1, title:'bar'},
  {id: 2, title:'baz'},
]

const fn = (x,y) => x.title === y.title

const result = R.uniqWith(fn, arr)

console.log(result === expectedResult) // => true

update

update(i: number, replaceValue: T, arr: T[]): T[]

It returns a new copy of the arr with the element at i index replaced with replaceValue.

// => ['foo', baz]

without

without(a: T[], b: T[]): T[]

It will return a new array based on b array.

This array contains all members of b array, that doesn't exist in a array.

Method R.equals is used to determine the existance of b members in a array.

R.without([1, 2], [1, 2, 3, 4])
// => [3, 4]

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']]

zipObj

zipObj(a: K[], b: V[]): Object

It will return a new object with keys of a array and values of b array.

R.zipObj(['a', 'b', 'c'], [1, 2, 3])
//=> {a: 1, b: 2, c: 3}

// truncates to shortest list
R.zipObj(['a', 'b', 'c'], [1, 2])
//=> {a: 1, b: 2}
