array arr list include whitelist with items elements values filter

array-move - Move an array item to a different position

•    Javascript

---

Returns a new array with the item moved to the new position.Moves the item to the new position in the input array. Useful for huge arrays where absolute performance is needed.

array arr set uniq unique duplicate remove union combine merge

array-uniq - Create an array without duplicates

•    Javascript

---

Create an array without duplicates

array arr set uniq unique duplicate remove

arrify - Convert a value to an array

•    Javascript

---

Supplying null or undefined results in an empty array.

arr-diff - Returns an array with only the unique values present in all given arrays using strict equality for comparisons

•    Javascript

---

Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons. Returns the difference between the first array and additional arrays.

arr-flatten - Recursively flatten an array or arrays

•    Javascript

---

Recursively flatten an array or arrays. I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.

arr-map - Faster, node.js focused alternative to JavaScript's native array map.

•    Javascript

---

Faster, node.js focused alternative to JavaScript's native array map. JavaScript's native Array.map() is slow, and other popular array map libraries are focused on browser compatibility, which makes them bloated or less than idea for non-browser usage. This implementation is focused on node.js usage keeping it light and fast.

array-sort - Fast and powerful array sorting

•    Javascript

---

Fast and powerful array sorting. Sort an array of objects by one or more properties. Any number of nested properties or custom comparison functions may be used. If custom functions are supplied, array elements are sorted according to the return value of the compare function. See the docs for Array.sort() for more details.

filter-object - Return a copy of an object, filtered to have only keys that match the given glob patterns

•    Javascript

---

Filter an object by its keys or values. Returns a copy of an object filtered to have only keys or values that match the given glob patterns. See glob-object and/or filter-values for the full range of options and available features.

map-arr - MOVED! See link :point_right:

•    Javascript

---

My motivation for faster-than-native Array.prototypes continued! This module is part of the bunch. Although the collection is still actively WIP, you may go here for further updates.
