Node.js provides streams, which are continuous flows of data that can be read or written in chunks, allowing for efficient handling of large amounts of data without consuming excessive resources. Three primary stream types exist: readable, writable, and duplex streams. Stream pipelines consist of connected streams processing data in a linear fashion, performing operations like filtering, mapping, or transforming it.
Node.js provides a built-in `stream` module for handling large datasets with ease. Streams process data in chunks, offering memory efficiency and scalability. Two primary stream types are Readable (reads from source) and Writable (writes to destination). Stream pipelines chain multiple instances together, allowing complex operations on large datasets. A practical example demonstrates processing large JSON files using streams.
