# jointNames

The names of the joints in the pose in specific order.

```
var jointNames: [String] { get set }
```

## Discussion

Each joint name has a corresponding transformation value in [`jointTransforms`](/documentation/RealityKit/SkeletalPose/jointTransforms) at the same index.

Updates of the value results in resizing or reordering of the pose’s [`jointTransforms`](/documentation/RealityKit/SkeletalPose/jointTransforms) to match.
New joint names add identity transformations at the matching indices.
