## Install

```bash
npm install --save 2djs
```

or,

```bash
yarn add 2djs
```

## API

### `constructor`

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

### `get()`

```js
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()`

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

### `clear()`

```js
array.clear(); // []
```

### `rowSize()`

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

### `columnSize()`

```js
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)`

```js
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)`

```js
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]
array.row(2); // [9, 10, 11, 12]
```

### `column(position)`

```js
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]
array.column(2); // [3, 7, 11]
```

### `rows()`

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

### `columns()`

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

### `firstRow()`

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

### `firstColumn()`

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

### `lastRow()`

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

### `lastColumn()`

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

### `add(twoDimensionalArray)`

```js
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] ];
array.add(arr); // [ [ 1, 2, 3, 4 ], [ 5, 6, 7, 8 ], [ 9, 10, 11, 12 ], [ 13, 14, 15, 16 ], [ 17, 18, 19, 20 ] ]

### `addRow(row)`

```js
const items = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], ];
const array = new TwoDimensionalArray(items);
array.addRow([13, 14, 15, 16]); // [ [ 1, 2, 3, 4 ], [ 5, 6, 7, 8 ], [ 9, 10, 11, 12 ], [ 13, 14, 15, 16 ] ]
```

### `addColumn(column)`
