# functional.js (λ) [![Build Status](https://travis-ci.org/leecrossley/functional-js.png?branch=master)](https://travis-ci.org/leecrossley/functional-js) [![npm version](https://badge.fury.io/js/functional.js.png)](https://npmjs.org/package/functional.js) [![devDependency Status](https://david-dm.org/leecrossley/functional-js/dev-status.png)](https://david-dm.org/leecrossley/functional-js#info=devDependencies)
functional.js is a functional JavaScript library. It facilitates [currying](http://en.wikipedia.org/wiki/Currying) and [point-free / tacit](http://en.wikipedia.org/wiki/Tacit_programming) programming.
<img align="right" src="http://functionaljs.com/css/images/logo@2x.png">
**functional.js is a functional JavaScript library.**
## Getting started
It facilitates [currying](http://en.wikipedia.org/wiki/Currying) and [point-free / tacit](http://en.wikipedia.org/wiki/Tacit_programming) programming.
### Using npm
### Documentation
```
npm install functional.js
```
Visit [functionaljs.com](http://functionaljs.com/) for the full documentation.
To then include functional.min.js in your app:
### Quick example
```
var λ = require("functional.js");
```
### Direct dependency
Download the minified version [here](http://bit.ly/funcmin), reference the js file and λ will become a global variable.
### Using client side
There are possible issues with using the "λ" character client side. There shouldn't be, but there are. If you experience issues, there is an alternative client version, functional.min.client.js which uses "lambda" instead of "λ". Download the minified client version [here](http://bit.ly/funcclient), reference the js file and lambda will become a global variable.
## Examples
### Basic λ.curry example
```javascript
var concatenate = λ.curry(function(word1, word2) {
return word1 + " " + word2;
});
var concatenateHello = concatenate("Hello");
var result = concatenateHello("World");
expect(result).toEqual("Hello World");
```
### Another λ.curry example
```javascript
var add = λ.curry(function(arg1, arg2, arg3) {
return arg1 + arg2 + arg3;
});
var add3 = add(3),
add5 = add3(2);
expect(add(3)(2)(1)).toEqual(6);
expect(add3(2, 1)).toEqual(6);
expect(add3(2)(1)).toEqual(6);
expect(add5(1)).toEqual(6);
```
### Extending arity with λ.curry example
```javascript
var add = λ.curry(function(arg1, arg2) {

### Curried λ.each example
```javascript
var result = [],
items = ["f", "u", "n", "c"];
var addTo = function (item) {
return result.push(item);
};
var addToResult = λ.each(addTo);
expect(typeof (addToResult)).toEqual("function");

### Curried λ.map example
```javascript
var items = [1, 2, 3];
var doubleUp = function (number) {
return number * 2;
};
var doubleMap = λ.map(doubleUp);
expect(typeof (doubleMap)).toEqual("function");
var result = doubleMap(items);
expect(result).toEqual([2, 4, 6]);

### Curried λ.reduce example
```javascript
var items = [1, 2, 3];
var multiply = function (arg1, arg2) {
return arg1 * arg2;
};
var multiplyReduceFrom1 = λ.reduce(multiply, 1);
expect(typeof (multiplyReduceFrom1)).toEqual("function");
var result = multiplyReduceFrom1(items);
expect(result).toEqual(6);
```
### Curried λ.any example
```javascript
var items1 = [1, 2, 3],
items2 = [1, 3, 5];
var even = function (item) {
return item % 2 === 0;
};
var anyEven = λ.any(even);
expect(anyEven(items1)).toBeTruthy();
expect(anyEven(items2)).not.toBeTruthy();
```
### Curried λ.select example
```javascript
var items = [1, 2, 3, 4, 5];
var even = function (item) {
return item % 2 === 0;
};
var odd = function (item) {
return item % 2 !== 0;
};
var selectEven = λ.select(even);
var selectOdd = λ.select(odd);
expect(selectEven(items)).toEqual([2, 4]);
expect(selectOdd(items)).toEqual([1, 3, 5]);
```
### Curried λ.first example
```javascript
var items = [5, 4, 3, 2, 1];
var even = function (item) {
return item % 2 === 0;
};
var odd = function (item) {
return item % 2 !== 0;
};
var firstEven = λ.first(even);
var firstOdd = λ.first(odd);
expect(firstEven(items)).toEqual(2);
expect(firstOdd(items)).toEqual(1);
```
### Curried λ.last example
```javascript
var items = [5, 4, 3, 2, 1];
var even = function (item) {
return item % 2 === 0;
};
var odd = function (item) {
return item % 2 !== 0;
};
var lastEven = λ.last(even);
var lastOdd = λ.last(odd);
expect(lastEven(items)).toEqual(2);
expect(lastOdd(items)).toEqual(1);
```
### Curried λ.best example
```javascript
var words = ["simply", "the", "best"];
var longest = λ.best(function (arg1, arg2) {
return arg1.length > arg2.length;
});
expect(typeof (longest)).toEqual("function");
expect(longest(words)).toEqual("simply");
```
### Curried λ.every example
```javascript
var items = [2, 4, 6, 8];
var even = function (item) {
return item % 2 === 0;
};
var odd = function (item) {

};
var everyEven = λ.every(even);
var everyOdd = λ.every(odd);
expect(everyEven(items)).toEqual(true);
expect(everyOdd(items)).toEqual(false);
```
### Multiple λ.compose example
```javascript
var e = function (a) {
return "hello " + a;
};
var f = function (a) {
return a + 1;
};
var g = function (a) {
return a * 100;
};
var composed = λ.compose(e, f, g);
expect(composed(2)).toEqual("hello 201");
```
### Curried λ.partition example

var even = function (item) {
return item % 2 === 0;
};
var partitionEven = λ.partition(even);
var result = partitionEven(items);
expect(result).toEqual([[6, 4, 2], [7, 5, 3, 1]]);

"p1": "abc",
"p2": false,
"p3": null

### λ.apply example
