| Reorder elements within array by index. | |
| [](https://npmjs.org/package/array-rearrange/) | |
| ```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. | |
