array Array.prototype.column (index)

Return the values from a single column

[
    [1,2,3,4,5],
    [6,7,8,9,0],
    [1,3,4,6,9]
].column(0) // returns [1,6,1]

boolean Array.prototype.empty ()

Truncate Array

var a = [1,2,3,4,5,6,7,8,9,0];
a.empty();
console.log(a); // returns []

* Array.prototype.end ()

IMPORTANT: Alias of last

Get the last item

[1,2,3,4,5,6,7,8,9,0].end() // returns 0

boolean Array.prototype.exists (index)

Check if item exists by index

[1,2,3,4,5,6,7,8,9,0].exists(0)  // returns true
[1,2,3,4,5,6,7,8,9,0].exists(-1) // returns false
[1,2,3,4,5,6,7,8,9,0].exists(10) // returns false
[1,2,3,4,5,6,7,8,9,0].exists(9)  // returns true

* Array.prototype.get(index, _default)

Get a item by index. If it not exists, return you own default value

[1,2,3,4,5,6,7,8,9,0].get(0) // returns 1
[1,2,3,4,5,6,7,8,9,0].get(-1, false) // returns false
[1,2,3,4,5,6,7,8,9,0].get(-1) // returns undefined

boolean Array.prototype.isEmpty ()

Check if a empty Array

var a = [];
var b = [1,2,3,4,5,6,7,8,9,0];
a.isEmpty() // returns true
b.isEmpty() // returns false

boolean Array.prototype.left (index)

Move item to left position by index

[1,2,3,4,5,6,7,8,9,0].left(0); // returns [1,2,3,4,5,6,7,8,9,0]
[1,2,3,4,5,6,7,8,9,0].left(9); // returns [1,2,3,4,5,6,7,9,8,0]

boolean Array.prototype.move (from, to)

Move a item by index position to a new index position

[0,1,2,3,4,5,6,7,8,9].move(0, 9); // returns [1,2,3,4,5,6,7,8,9,0]

boolean Array.prototype.remove (index)

Remove a item by index

[1,2,3,4,5,6,7,8,9,0].remove(0); // returns true
// produces
// [2,3,4,5,6,7,8,9,0]

boolean Array.prototype.right (index)

Move item to right position by index

[1,2,3,4,5,6,7,8,9,0].right(0); // returns [1,2,3,4,5,6,7,8,9,0]
[1,2,3,4,5,6,7,8,9,0].right(9); // returns [1,2,3,4,5,6,7,9,8,0]

array Array.prototype.shuffle ()

Shuffle array

[1,2,3,4,5,6,7,8,9,0].shuffle();

* Array.prototype.start ()

IMPORTANT: Alias of first

Get the first item

[1,2,3,4,5].start() // returns 1

number Array.prototype.sum ()

Calculate the sum of values

[1,2,3,4].sum() // returns 10

boolean Array.prototype.down (index)

IMPORTANT: Alias of right

Move item to right position by index

[1,2,3,4,5,6,7,8,9,0].down(0); // returns [1,2,3,4,5,6,7,8,9,0]
[1,2,3,4,5,6,7,8,9,0].down(9); // returns [1,2,3,4,5,6,7,9,8,0]

* Array.prototype.first ()

Get the first item

[1,2,3,4,5,6,7,8,9,0].first() // returns 1

* Array.prototype.last ()

Get the last item

[1,2,3,4,5,6,7,8,9,0].last() // returns 0

boolean Array.prototype.up (index)

IMPORTANT: Alias of left

Move item to up position by index

[1,2,3,4,5,6,7,8,9,0].up(0); // returns [1,2,3,4,5,6,7,8,9,0]
[1,2,3,4,5,6,7,8,9,0].up(9); // returns [1,2,3,4,5,6,7,9,8,0]
