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.

(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 ]
|
||
|
|
```
