> 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}
> Thanks to Thiago for the suggestions!
