nub

Return all the unique elements of an array. You can specify your own uniqueness
comparison function with nub.by too.

These work like haskell's
nub
and
nubBy
functions in
Data.List.

example

`` js
$ node
> var nub = require('nub')
> nub([1,2,2,3,1,3])
[ 1, 2, 3 ]
> nub.by([ 2, 3, 5, 7, 8 ], function (x,y) { return x + y === 10 })
[ 2, 3, 5 ]
`

methods

` js
var nub = require('nub')
`

nub(xs)

Return a new array with all the uniqe elements in xs.

Uniqueness is calculated === style so the types matter.

nub.by(xs, cmp)

Use cmp(x,y) function to compare elements instead of the default.
cmp should return whether the two elements are equal as a boolean.

install

With npm do:

`
npm install nub
``

To use nub in the browser, use browserify or fetch a
UMD build from browserify CDN.
