# remove-array-items
remove items from a javascript array without generating memory garbage.
[](https://travis-ci.org/mreinstein/remove-array-items)
Despite there being a number of "remove array items" in npm, I couldn't find satisfying all criteria:
* **doesn't generate garbage**
* **performs similar or better to the native `array.splice`**
* has tests
* es3+ compatible
so here we are.
originally inspired by https://gamealchemist.wordpress.com/2013/05/01/lets-get-those-javascript-arrays-to-work-fast/
(which is a gold mine for performant, non-garbage generating array operations by the way.)
## api
```javascript
removeItems(arr, startIdx, removeCount)
```
## usage
```javascript
const removeItems = require('remove-array-items')
const arr = [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
removeItems(arr, 3, 4) // after running, arr === [ 1, 2, 3, 8, 9 ]
```
