asfimport opened a new issue, #105:
URL: https://github.com/apache/arrow-js/issues/105
The .toArray() javascript method of vectors includes a shortcut to return
the underlying typed array; but this doesn't respect null values, and so can
return the wrong number.
```
v = arrow.Vector.from(\{values: [1, 2, 3, 4, 5, null, 6],type: new
arrow.Int32()})
v.toArray()[5] // Incorrectly returns '0'
v.get(5) // Correctly returns null
```
Solution: Eliminate the fast method, always return Javascript arrays. It
might be better to keep the old method in cases where there are guaranteed no
nulls.
