A collection of useful methods to extend Arrays.

• Array

Calls Math.min on the array and returns its lowest value.

myArray.min();

[1, 2, 3].min();
//returns 1

• (number) the lowest number in the array

Calls Math.max on the array and returns its highest value.

myArray.max();

[1, 2, 3].max();
//returns 3

• (number) the highest number in the array

Calculates the average value of the array.

myArray.average();

[1, 2, 3].average();
//returns 2

• (number) the average value of the array

Randomizes the array (altering it).

myArray.shuffle();

[1, 2, 3].shuffle();

• (array) the array.

Calling this method alters the array; it doesn't just return a new array with the same contents shuffled. It does, however, return itself.

Sums up all values in an array.

myArray.sum();

$$('ul.menu li').getWidth().sum();
//returns the width of all li elements inside ul.menu as a sum

• (number) a number containing the sum of all values in the given array

Returns a new array without duplicate values.

myArrayWithoutDupes = myArray.unique();

var fruits = ['apple', 'lemon', 'pear', 'lemon', 'apple'].unique();
//fruits == ['apple', 'lemon', 'pear']

• (array) a new array without duplicates.
