Adding this description to both docstrings would be a helpful clarification IMO.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1674532233

This API allows masking using just
```python
arr.where(mask)

```python
da = xr.DataArray(np.arange(10))
print(xr.where(da < 5, da, 0).values)
print(da.where(da < 5, 0).values)
