|
||
|
|
|
||
|
|
```js
|
||
|
|
const reorder = require('array-rearrange')
|
||
|
|
|
||
|
|
let arr = reorder([9,8,7,6], [3,2,1,0]) // [6,7,8,9]
|
||
|
|
|
||
|
|
let arr2 = reorder([3,3, 2,2, 1,1], [2,1,0]) // [1,1, 2,2, 3,3]

## API
|
||
|
|
|
||
|
|
### array = reorder(array, index, stride=1)
|
||
|
|
|
||
|
|
Shuffle elements in `array` according to the `index` array passed. Permutes original array. `index` array should contain unique indexes. Pass `stride` to indicate groups of elements to shuffle.
|
||
|
|
|
||
|
|
Originally based on the [reference solution](https://www.geeksforgeeks.org/reorder-a-array-according-to-given-indexes/), which turns out to be wrong, so algorithm is fully rewritten.
