Research direction
Examine the existing typed array implementations in Rhino (e.g., Int32Array) to understand the required patterns and interfaces. Implement BigInt64Array and BigUint64Array following the same structure, including constructor, getter, setter, and length property. For DataView, add getBigInt64 and getBigUint64 methods mimicking the existing getInt32 and getUint32 methods. Refer to MDN documentation for exact semantics.
