Explain the concept of object streams and provide an example use case.
By default, Node.js streams deal with Buffer or string data, but object streams make it easier to handle structured data, such as JSON objects, arrays, or even complex custom objects.
To create or use an object stream, the objectMode property must be set to when creating a stream. This enables the stream to work with JavaScript objects rather than just bytes or characters.
Example Use Cases
Data Transformation Pipelines: Converting data formats (e.g., JSON to CSV). Normalizing data (e.g., modifying or restructuring object properties).
Logging Systems: Streaming log entries as structured objects for storage or analysis
Database Operations: Streaming objects from a database query and transforming or processing them before writing them to another source.
