API

constructor

import TwoDimensionalArray from '2djs';
const items = [
  [1, 2, 3, 4],
  [5, 6, 7, 8],
  [9, 10, 11, 12],
];
const array = new TwoDimensionalArray(items);

get()

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.get(); // [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ]

stat()

console.log(array.stats());
{
  rowSize: 3,
  columnSize: 4
};

clear()

array.clear(); // []

rowSize()

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.rowSize(); // 3

columnSize()

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.columnSize(); // 4

at(rowPosition, columnPosition)

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.at(0, 0); // 1
array.at(2, 2); // 11
array.at(10000, 0); // null

row(position)

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.row(0); // [1, 2, 3, 4]

column(position)

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.column(0); // [1, 5, 9]

add(twoDimensionalArray)

const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
const arr = [ [13, 14, 15, 16], [17, 18, 19, 20] ];
