---------------------------------------
Summary: [JS] Table.from fails for zero-item Lists,
FixedSizeLists, Maps. ditto Table.empty
Key: ARROW-9479
URL: https://issues.apache.org/jira/browse/ARROW-9479
Project: Apache Arrow
Issue Type: Bug
Components: JavaScript
Affects Versions: 0.17.1
Reporter: Nicholas Roberts
deserializing zero-item tables (as generated by Table.empty or, in this case,
pyarrow.Schema.serialize) with a schema containing a List, FixedList or Map
fail due to an unconditional
{code:java}
new Data(/* preceding parameters */ buffers, [childData]){code}
statement, the childData parameter resolves to [undefined] rather than the
desired [].
