**Functional tools that couldn’t be simpler.**
We’re proud to present *1-liners* – a dead simple functional utility belt. **[137 one-liner functions][docs]** (and counting). Each hand-crafted with love and attention.
[docs]: ./documentation
## 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. 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
```js
// The lightweight, recommended way:
var map = require('1-liners/map');
// Sometimes practical:
var map = require('1-liners').map;
```
### Usage in ES 2015 (formerly ES6)
```js
// The lightweight, recommended way:
import map from '1-liners/module/map';
// Sometimes practical:
import { map, filter } from '1-liners/module';
```
