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

vara=[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

vara=[];varb=[1,2,3,4,5,6,7,8,9,0];a.isEmpty()// returns trueb.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]
