1. You can't ever get a reference to regular objects that exist in other threads (workers). Communication with workers is limited to sending strings, copies of JSON objects, transfers of typed arrays, and references to SharedArrayBuffers.

2. I assume it was done at a low level so that multi-threaded C++ could be compiled to javascript (asm.js/WebAssembly).

For (1) does this mean that everything in the global namespace barfs when called from a worker thread?

(2) sounds like it might need a larger set of primitives, though I'm not sure.

1. Web workers don't share a javascript namespace or anything with the parent page. They're like a brand new page (that happens to not have a DOM). Outside of SharedArrayBuffer, there's no shared memory.
