Dominik Moritz updated ARROW-12536:
-----------------------------------
Description:
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!
