What is the primary use case for Node Worker Threads and Child Processes 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 Worker Threads and Child Processes?

Developers often forget to handle asynchronous errors or improperly manage memory, leading to memory leaks and blocked event loops.

1The SharedArrayBuffer

The biggest advantage of Worker Threads over Child Processes is SharedArrayBuffer. Instead of copying 1GB of image data to the child process (which uses another 1GB of RAM), the main thread and the worker thread can both look at the exact same 1GB memory block simultaneously.
