Since they're sharing memory I will call them threads :)

No, they are not sharing.

The data is copied rather than shared.

But what about

The worker context is represented by a DedicatedWorkerGlobalScope object in the case of dedicated workers (standard workers that are utilized by a single script; shared workers use SharedWorkerGlobalScope). A dedicated worker is only accessible from the script that first spawned it, whereas shared workers can be accessed from multiple scripts.

I'm confused now

[elizarov]

"Shared workers” has nothing to do with data/memory sharing. In this sense, all processes in OS are “shared”, because they can communicate.

[elizarov]

They key distinctions between threads and processes is that processes have private memory (data), while threads share memory (data) between them. In this sense, WebWorkers are processes.

I understand, thank you :)
