λ = require('core.lambda')
 
function add2(ab) { return a + b }
var add = λ.curry(add2)
 
λ.compose(add(1), λ.compose( λ.uncurry(add2)
                           , λ.constant([2, 3])))()
// => 6 

The easiest way is to grab it from NPM. If you're running in a Browser environment, you can use [Browserify][]

$ npm install core.lambda

If you're not using NPM, [Download the latest release][release], and require the core.lambda.umd.js file:

var Lambda = require('core.lambda')

[Download the latest release][release], and require the core.lambda.umd.js file:

require(['core.lambda'], function(Lambda) {
  ( ... )
})

[Download the latest release][release], and load the core.lambda.umd.js file. The properties are exposed in the global folktale.core.lambda object:

<script src="/path/to/core.lambda.umd.js"></script>

If you want to compile this library from the source, you'll need [Git][], [Make][], [Node.js][], and run the following commands:

$ git clone git://github.com/folktale/core.lambda.git
$ cd core.lambda
$ npm install
$ make bundle

This will generate the dist/core.lambda.umd.js file, which you can load in any JavaScript environment.

You can [read the documentation online][docs] or build it yourself:

$ git clone git://github.com/folktale/core.lambda.git
$ cd core.lambda
$ npm install
$ make documentation

Then open the file docs/index.html in your browser.

This library assumes an ES5 environment, but can be easily supported in ES3 platforms by the use of shims. Just include [es5-shim][] :)
