nodash

Build Status Dependencies Dependencies

nodash offers you a rich set of library functions, comparable to the likes of underscore or lodash. The functions are actually derived from the Haskell Prelude and emphasize a functional programming style.

A special trait of this library is that it discards some JavaScript concepts (like prototypes or optional arguments) to allow some (in the authors opinion) more useful ones (such as currying).

Every function from this library can be thought of as curried, i.e. you can partially apply any function and get a function in return (on the other hand this means there are no optional arguments). It also supports lists which can be evaluated lazily and infinite streams.

Browse through the apidoc, benchmark, or tests for examples.

For a list of which prelude functions are covered see the apidoc appendix.

Nodash is available via npm.

Example

Nodash.install(global || window); // node or browser
 
var reverse = foldl(flip(cons), []);
 
console.log(reverse([1,2,3])); // → [3,2,1]

Usage

in node

npm install --save nodash
var Nodash = require('nodash');

in the browser

<script src="nodash.js"></script>
<script>
    // Nodash is available in `window.Nodash`
    document.write(Nodash.foldl(Nodash.flip(cons), []));
</script>

in legacy browsers

Just pull in es5-shim first:

<script src="https://cdnjs.cloudflare.com/ajax/libs/es5-shim/4.1.13/es5-shim.js"></script>
<script src="nodash.js"></script>

install(mountpoint)

It is possible to attach the Nodash functions directly to the global object (in fact, any object), optionally with a prefix or postfix:

Nodash.install(global);           → foldl(flip(cons), []);
Nodash.install([ '$', global ]);  → $foldl($flip($cons), []);
Nodash.install([ global, '_' ]);  → foldl_(flip_(cons_), []);
Nodash.install([ 'f_', global ]); → f_foldl(f_flip(f_cons), []);

Both a prefix and a postfix works too:

Nodash.install([ '__', global, '__' ]); → __foldl__(__flip__(__cons__), []);
