3 Removes all duplicates from an array in place.
7 First install using npm:
11 Then use it as follows:
15 var arr = [1, 1, 2, 2, 3, 5]
26 ## `require("uniq")(array[, compare, sorted])`
27 Removes all duplicates from a sorted array in place.
29 * `array` is the array to remove items from
30 * `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.
31 * `sorted` if true, then assume array is already sorted
33 **Returns:** A reference to `array`
35 **Time Complexity:** `O(array.length * log(arra.length))` or `O(array.length)` if `sorted`
38 ## Why use this instead of underscore.uniq[ue]?
41 * This library updates the array in place without making an extra copy (and so it is faster for large arrays)
42 * It also accepts a custom comparison function so you can remove duplicates from arrays containing object
43 * It is more modular in the sense that it doesn't come with a bazillion other utility grab bag functions.
