<a id="function-spliceArray">

### `spliceArray( targetArray, insertArray, index ) → void`

Splices one array into another. To be used instead of `Array.prototype.splice` for better performance and because the latter may throw "Maximum call stack size exceeded" error when passing huge number of items to insert.

```typescript
spliceArray( [ 1, 2 ], [ 3, 4 ], 0 );	// [ 3, 4, 1, 2 ]
spliceArray( [ 1, 2 ], [ 3, 4 ], 1 );	// [ 1, 3, 4, 2 ]
spliceArray( [ 1, 2 ], [ 3, 4 ], 2 );	// [ 1, 2, 3, 4 ]
spliceArray( [ 1, 2 ], [],	   0 );	// [ 1, 2 ]
```
