[jira] [Created] (ARROW-3336) JS writer doesn't serialize sliced Vectors correctly

Paul Taylor created ARROW-3336:
----------------------------------

             Summary: JS writer doesn't serialize sliced Vectors correctly
                 Key: ARROW-3336
                 URL: https://issues.apache.org/jira/browse/ARROW-3336
             Project: Apache Arrow
          Issue Type: Improvement
          Components: JavaScript
    Affects Versions: JS-0.3.1
            Reporter: Paul Taylor
            Assignee: Paul Taylor
             Fix For: JS-0.4.0


The JS IPC writer is slicing the data and valueOffset buffers by starting from the data's current logical offset. This is incorrect, since the slice function already does this for the data, type, and valueOffset TypedArrays internally. PR incoming.
