Dominik Moritz updated ARROW-12536:
-----------------------------------
Summary: [JS] Construct tables from JavaScript types (was: [JS] Construct
tables from an iterable of objects or js array columns)
> [JS] Construct tables from JavaScript types
> -------------------------------------------
>
> Key: ARROW-12536
> URL: https://issues.apache.org/jira/browse/ARROW-12536
> Project: Apache Arrow
> Issue Type: Improvement
> Components: JavaScript
> Reporter: Dominik Moritz
> Priority: Major
>
> Right now, Arrow has no automatic type inference for JavaScript types, so I
> think we would need to add that.
> {code:javascript}
> // Convert from JS types automatically
> const t = Arrow.Table.from({
> Country: ["USA", "Canada", "Mexico"],
> GDP: [123, 234, 345],
> })
> // I'd also like Arrow to support other common JS table formats:
> const t = Arrow.Table.from([
> {Country: "USA", GDP: 123},
> {Country: "Canada", GDP: 234},
> {Country: "Mexico", GDP: 345},
> ])
> const t = Arrow.Table.from([
> ["Country", "GDP"],
> ["USA", 123],
> ["Canada", 234],
> ["Mexico", 345],
> ])
> {code}
