A module that loads some modules that are useful in javascript, for objects and arrays
Installation

Usage
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]
