What is Streams?
Streams in Node.js are objects that let you read or write data in chunks, rather than loading everything into memory at once. They are useful for handling large files, HTTP requests, or any data that comes in over time. There are four types: readable, writable, duplex (both), and transform (modifies data as it passes through).
