uniq ==== 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. # Credits (c) 2013 Mikola Lysenko.
