# unordered-array-remove
|
|
|
|
Efficiently remove an element from an unordered array without doing a splice
|
|
|
|
```
|
|
npm install unordered-array-remove
|
|
```
|
|
|
|

|
|
|
|
## Usage
|
|
|
|
``` js
|
|
var remove = require('unordered-array-remove')
|
|
|
|
var list = ['a', 'b', 'c', 'd', 'e']
|
|
remove(list, 2) // remove 'c'
|
|
console.log(list) // returns ['a', 'b', 'e', 'd'] (no 'c')
|
|
```
|
|
|
|
This works by popping the last element (which is fast because it doesn't need shift all array elements)
|
|
and overwriting the removed index with this element.
