[jira] [Commented] (ARROW-2765) [JS] add Vector.map

    [ https://issues.apache.org/jira/browse/ARROW-2765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16528181#comment-16528181 ] 

Brian Hulette commented on ARROW-2765:
--------------------------------------

To be consistent with JS typed arrays, I think {{Vector.map}} should return the same type as the source vector, and we can add {{Vector.from(source, f)}} to change types. What do you think of that [~paul.e.taylor]?
