100% agree on points mentioned above. I'm also curious if there is built-in
Arrow functionality to handle casting to native Javascript types.
My workaround:
```typescript
import { Table } from 'apache-arrow'
import { mapValues } from 'lodash'
export const arrowTableToRecords = (arrow: Table): Record<string, any>[] => {
// this does not handle BigInts, can't override prototype because it
refers to private symbol
// const after = arrow.toArray().map((row) => row.toJSON())
return arrow.toArray().map((obj: object) => {
return mapValues(obj, (v: any) => {
if (typeof v === 'bigint') {
if (v < Number.MIN_SAFE_INTEGER || v >
Number.MAX_SAFE_INTEGER) {
throw new TypeError(`${v} is not safe to convert to a
number.`)
}
return Number(v)
}
return v
})
})
}
```
LMK if others have a better way to do this.
