Package Exports
- uniq
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (uniq) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
uniq
Removes all duplicates from an array in place.
Usage
First install using npm:
npm install uniqThen 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.
arrayis the array to remove items fromcompareis 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.sortedif 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.
