Maybe `replace_in_data` or `update_data` would be appropriate names for a `DataArray` method that uses a dictionary as an argument? Then updating a coordinate would be solved with something like:
e.g.,
```python
da['two'] = da['two'].replace_in_data({'dd': 'd'})

A dedicated method would be nice though :).

""rename"" is understandably overloaded ... would something like ""update_coords"" be workable?  It sort of matches the existing ""assign_coords"".

Though I also find myself reaching for a method like pandas' `rename` occasionally.

Aside from the `rename` name, which I think is not good, what do others think about a method that takes a mapping and replaces values?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,834273555
