---------------------------------
Component/s: JavaScript
> [JS] Better BigInt compatibility check
> --------------------------------------
>
> Key: ARROW-11706
> URL: https://issues.apache.org/jira/browse/ARROW-11706
> Project: Apache Arrow
> Issue Type: Improvement
> Components: JavaScript
> Reporter: Diana Clarke
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h

> See: https://github.com/apache/arrow/pull/9110
> Check for whether {{BigInt64ArrayAvailable}} and {{BigUint64ArrayAvailable}}
> are available, rather than just {{BigIntAvailable}}. Recent versions of
> JavaScriptCore/WebKit in Safari support {{BigInt}} but do not support
> {{BigInt64Array}}, and so anything that relies on {{BigInt64Array}} will fail
> despite {{BigIntAvailable}} being true.
> The manifestation of this issue can be seen when trying to run the following
> within Safari on a table that contains bigints:
> {code:java}
> RecordBatchJSONWriter.writeAll(table).toString(true)
> message: "BigUint64Array is not available in this environment"
> BigUint64ArrayUnavailableError
> BigUint64ArrayUnavailable
> bignumToString
> bigNumsToStrings
> generatorResume@[native code]
> performIteration@[native code]
> visitInt
> visit
> map@[native code]
> recordBatchToJSON
> close
> finish
> global code
> {code}
