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
//

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.
