asfimport opened a new issue, #102:
URL: https://github.com/apache/arrow-js/issues/102

   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:
   ```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
   ```
