# Async WS:

Almost mirror (front and back) sample of:

Catching data from `Stream` or `WebSocket` and pass it as generated 
sequence of `Promise`s, which can be handled by pseudo synchronous 
`for ... of` or `for await ... of`

For solve this `Promise` with __outside control__ used. It needed
because data passed many times to stream `ondata`/`onmessage`/`onchunk`/`onfuckingsomethingelse` callback
not only once as in `Promise` callback. 

So, promises should be resolved from chunk event outside of 
closure, where `resolve` and `reject` accessible.

When chunk becomes, it saved into chunks queue, and if promise
for that chunk are already yielded, it resolves

When promise yielding outside of generator, if chunk for this promise
already saved in queue, promise resolves with data of that chunk

So, generated promises gives ability to handle stream in imperative
manner using `for of` loop with `await`.

Than, recieved messages passed as JSON with some RPC function call 
with params
