Paul Taylor commented on ARROW-9982: ------------------------------------ ¯\_(ツ)_/¯ We're getting complaints about how large and un-tree-shakeable the library is already. I don't see a reason to add more unrelated functionality, especially when it already exists in other tree-shakeable libraries like Ix. Otherwise, you can do `for...of` over any iterable type already, or have your own map implementation (no need to use Ix for something so simple) {code:javascript} function* map(source, project) { for (let x of source) yield project(x); } map(vector, (value) => console.log(value)); {code} > [JS] IterableArrayLike should support map > ----------------------------------------- > > Key: ARROW-9982 > URL: https://issues.apache.org/jira/browse/ARROW-9982 > Project: Apache Arrow > Issue Type: Improvement > Components: JavaScript > Reporter: Dominik Moritz > Priority: Minor > > `table.toArray()` returns an `IterableArrayLike` and I would like to be able > to `map` a function to it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
