set

Set.js

I created this because I noticed that there were no actual set object implementations in JavaScript and also to learn a bit more about creating node modules.

Usage

Create an array of items and then pass it to Set.
var Set = require('./set')
var set = new Set([0,1,1])
And then when we get it
set.get() // [0,1]

API

There are various Set functions available

Static functions

Set#unique given an array, return an array with all duplicates removed.

Set#size return the size of the Set.
