One of the biggest strengths of Node.js is its ability to process large amounts of data efficiently. Today, I explored Streams, one of the most important concepts for backend development and a frequently asked topic in Node.js interviews.
A Stream is a way to process data chunk by chunk instead of loading the entire file into memory.
Instead of reading a 2 GB file at once, Node.js reads small chunks (typically 64 KB for fs.createReadStream()), making applications much more memory-efficient and scalable.
Why use Streams?
A chunk is a small piece of data transferred by a stream.
