------------------------------------
Summary: [JS] Add DataFrame.toJSON
Key: ARROW-2202
URL: https://issues.apache.org/jira/browse/ARROW-2202
Project: Apache Arrow
Issue Type: Improvement
Components: JavaScript
Reporter: Brian Hulette
Currently, {{CountByResult}} has its own [{{toJSON}}
method|https://github.com/apache/arrow/blob/master/js/src/table.ts#L282], but
there should be a more general one for every {{DataFrame}}.
{{CountByResult.toJSON}} returns:
{code:json}
{
"keyA": 10,
"keyB": 10,
...
}{code}
A more general {{toJSON}} could just return a list of objects with an entry for
each column. For the above {{CountByResult}}, the output would look like:
{code:json}
[
{value: "keyA", count: 10},
{value: "keyB", count: 10},
...
]{code}
