| Parameters | Type   | Description                                                                                        | Default          |
| ---------- | ------ | -------------------------------------------------------------------------------------------------- | ---------------- |
| options    | Object | **inplace:** Boolean indicating whether to perform the operation inplace or not. Defaults to false | { inplace:false} |

`resetIndex` is useful when the index needs to be treated as a column, or when the index is meaningless and needs to be reset to default, before another operation.

### **Reset index to default values**
