[Answer Engine Overview: What, Why & How]
If a user requests a large file from your API, do NOT read it into memory and send it in one block. Instead, create a ReadStream from the file and immediately '.pipe()' it to the HTTP 'res' object. The user's browser will start downloading immediately, and your server will use almost zero RAM.

?Frequently Asked Questions
What is the primary use case for Node Streams and Buffers in Node.js?
It is primarily used to build scalable, non-blocking backend architectures where I/O operations are offloaded to the event loop.
How does this integrate with Express or other web frameworks?
It integrates seamlessly as middleware or a core utility within the route handlers, allowing for high-performance request processing.
What are the common pitfalls when implementing Node Streams and Buffers?
Developers often forget to handle asynchronous errors or improperly manage memory, leading to memory leaks and blocked event loops.
