47uniq
====
Removes all duplicates from an array in place.
Usage
=====
First install using npm:
npm install uniq
Then use it as follows:
```javascript
var arr = [1, 1, 2, 2, 3, 5]
require("uniq")(arr)
console.log(arr)
//Prints:
//
// 1,2,3,5
//
```
## `require("uniq")(array[, compare, sorted])`
Removes all duplicates from a sorted array in place.
* `array` is the array to remove items from
* `compare` is an optional comparison function that returns 0 when two items are equal, and something non-zero when they are different. If unspecified, then the default equals will be used.
* `sorted` if true, then assume array is already sorted
**Returns:** A reference to `array`
**Time Complexity:** `O(array.length * log(arra.length))` or `O(array.length)` if `sorted`
## Why use this instead of underscore.uniq[ue]?
A few reasons:
* This library updates the array in place without making an extra copy (and so it is faster for large arrays)
* It also accepts a custom comparison function so you can remove duplicates from arrays containing object
* It is more modular in the sense that it doesn't come with a bazillion other utility grab bag functions.
