Functional tools that couldn’t be simpler.

We’re proud to present 1-liners – a dead simple functional utility belt. 137 one-liner functions (and counting). Each hand-crafted with love and attention.










Our decalogue

You get a product of top-quality functional programming craftmanship. Each function follows the KISS principle, which we’ve broken down into ten strict rules.

We always follow them. You have our word.



1-liners


  1. Each function shall fit in one readable line of code
    – take a glimpse at the source and you know exactly what’s going on.
     

  2. Each function shall have no side-effects
    – you can use it with confidence.
     

  3. Each function shall have a fixed number of arguments
    – it’s dead easy to bind, curry and uncurry, apply partially, implode and explode.
     

  4. Each function shall deal with data in an immutable way
    – no more debugging nightmares.
     

  5. Each function shall take data as the last argument
    – this makes currying and composing new functions a breeze.
     

  6. Each function shall be in a separate micro-module
    – you only load/bundle the single 1-liner you need.
     

  7. Each function shall be thoroughly tested
    – 100% code coverage guaranteed. We even test if every function fits in one line!
     

  8. Each function shall have great documentation
    – the docs explain usage, present the source, and link to the specs.
     

  9. We shall provide functional versions of native object methods
    – like reduce(callback, array) for array.reduce(callback).
     

  10. We shall provide functional versions of language constructs
    – like plus(a, b) for a + b.
     

Usage

Install

$ npm install --save 1-liners

Usage in ES5

// The lightweight, recommended way:
var map = require('1-liners/map');

// Sometimes practical:
var map = require('1-liners').map;

Usage in ES 2015 (formerly ES6)

// The lightweight, recommended way:
import map from '1-liners/module/map';

// Sometimes practical:
import { map, filter } from '1-liners/module';
