Array.prototype.unique >= 0.1.2

Purpose

Get all the unique values and return them as a new array

Syntax

Array#uniqe ( Stringpath );

Parameters

path
Path to use to check for uniqueness

Return values

Array

A new array

Examples

Should return all the unique values

var arr = [1,2,1,3,6,2];

arr.unique();>>> [1, 2, 3, 6]

Handle object references

It will only return the same object once, but it won't look into an object's content

var obj = {a: 1},
    arr = [1,1, obj, {a:1}, obj];

arr.unique();>>> [1, {a: 1}, {a: 1}]

Use a path to determine uniqueness

You can use dot-notation paths, supported by Object.path

var arr = [
	{id: 'a'},
	{id: 'b'},
	{id: 'a'},
	{id: 'c'},
	{id: 'a'},
	{id: 'c'},
	{id: 'd'},
];

arr.unique('id');>>> [{id: 'a'}, {id: 'b'}, {id: 'c'}, {id: 'd'}]
