Re: [I] [JS] `vectorFromArray()` can't create Int64 from Number [arrow]

trxcllnt commented on issue #40051:

   The value is assigned to a `BigInt64Array()`, so the error you're seeing is just what happens when you don't use BigInts:
   ```shell
   $ node -p 'new BigInt64Array([1])'
   [eval]:1
   new BigInt64Array([1])
   ^
   
   TypeError: Cannot convert 1 to a BigInt
       at new BigInt64Array (<anonymous>)
       at [eval]:1:1
