## Installation

```bash

npm install sort-array-for-drag-and-drop

```

## Usage

### `moveElement`

```js

const {moveElement} = require('sort-array-for-drag-and-drop');

const array = [

  'A',

  'B',

  'C',

];

console.log(moveElement(array, 0, 2));  // -> ['B', 'A', 'C'] (Insert `array[0]` before `array[2]`)

console.log(moveElement(array, 0, 1));  // -> ['A', 'B', 'C'] (Insert `array[0]` before `array[1]`, not moved)

console.log(moveElement(array, 0, 0));  // -> ['A', 'B', 'C'] (Not moved)

console.log(moveElement(array, 0, 3));  // -> ['B', 'C', 'A'] (In the case of an index that is exceeded, it inserts to the end)

console.log(moveElement(array, 2, 0));  // -> ['C', 'A', 'B'] (Insert `array[2]` before `array[0]`)

console.log(moveElement(array, 2, 1));  // -> ['A', 'C', 'B'] (Insert `array[2]` before `array[1]`)

```

### `moveElementByValue`

```js

const {moveElementByValue} = require('sort-array-for-drag-and-drop');

// The values must be unique

const array = [

  'A',

  'B',

  'C',

];

console.log(moveElementByValue(array, 'A', 'C'));  // -> ['B', 'A', 'C'] (Insert 'A' before 'C')

console.log(moveElementByValue(array, 'A', 'C', true));  // -> ['B', 'C', 'A'] (Insert 'A' after 'C')

console.log(moveElementByValue(array, 'D', 'C'));  // -> Error! ('D' is not included)

```

### `moveElementBy`

```js

const {moveElementBy} = require('sort-array-for-drag-and-drop');

// The values must be unique

const a = {value: 'a'};

const b = {value: 'b'};

const c = {value: 'c'};

const array = [a, b, c];

// return to compare with values

function getValue(elem) {

  return elem.value;

}

console.log(moveElementBy(array, getValue, 'A', 'C'));  // -> [B, A, C] (Insert A before C)

console.log(moveElementBy(array, getValue, 'A', 'C', true));  // -> [B, C, A] (Insert A after C)

console.log(moveElementBy(array, getValue, 'D', 'C'));  // -> Error! (D is not included)
