uniq

Removes all duplicates from an array in place.

# Usage

First install using npm:

    npm install uniq

Then use it as follows:

var arr = [1, 1, 2, 2, 3, 5]
require("uniq")(arr)
console.log(arr)
//Prints:
//
// 1,2,3,5
//

## <tt>require("uniq")(array[, compare, sorted])</tt>

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.
