I'm not fan of having the first ``.get`` on the next line and not right after ``storage``, it makes it look like ``storage`` is alone. 
```javascript
storage.get(KEY)
       .then(function () { 
           if (value) { ; }
       });
```
or
```javascript
storage.get(KEY)
    .then(function () { 
        if (value) { ; }
    });
```
or
```javascript
storage
    .get(KEY)
    .then(function () { 
        if (value) { ; }
    });
```
I think I prefer the first one.
