Re:A guide to threads in Node.js

SharedArrayBuffer -> shared
ArrayBuffer -> ownership can be transferred around, but the data can only be owned by one thread at a time. The data itself isn't copied. Passing around ArrayBuffers back and forth is good enough for a lot of stuff. In a worker you can then put a node Buffer, TypedArray, or DataView around the ArrayBuffer again, if you want.
Supposedly SharedArrayBuffer and atomics have been in Node.js since version 9.
I wonder if there are any articles where people use them in threads.
But else, yes, the sent and received data is serialized (when using ipc, else you can also send raw data through streams, and handle the serialization yourself)
