• keyway
• isUnique
• getUnique

xcept

Object

Omit object key-values

{ "a": "some value", "b": "other value", "c": "more value" }.omit(a).omit(c) // { "b": "other value" } 
{ "a": "some value", "b": "other value", "c": "more value" }.except(a).except(c) // { "b": "other value" } 

Array

Omit array elements

[1, 2, 3, 4, 5].omit(1).omit(2).omit(3) // [4, 5]
[1, 2, 3, 4, 5].except(1).except(2).except(3) // [4, 5]

kontains

Object

Checks if an object contains an element

{"elm1": "one", "elm2": "two"}.contains("elm1") // true 
{"elm1": "one", "elm2": "two"}.contains("elm2") // true 
{"elm1": "one", "elm2": "two"}.contains("one")  // false
{"elm1": "one", "elm2": "two"}.contains("ELM2") // false

Array

Checks if an array contains an element

[1, 2, 3].contains(1)   // true
[1, 2, 3].contains(one) // false

keyway

Transforms an array into an object

var arr = ["one", "two"];
obj = Array.keyway(arr) // obj = { "one": "", "two": ""}
obj = arr.keyway()      // obj = { "one": "", "two": ""}

isUnique

Returns true if the array only has unique elements. Otherwise, return false

[1].isUnique() // true
[1,2].isUnique() // true
[1,1].isUnique() // false

getUnique

Gets the unique version of the array. If there are two matching elements, the latter is removed

[1].getUnique() // [1] 
[1,1].getUnique() // [1] 
[1,2].getUnique() // [1,2]
[1,2,1,2].getUnique() // [1,2]
[1,2,2,2].getUnique() // [1,2]
