Is there some (even dumb) implementatio of `runBlocking` for JS?

The project I'm working has this: `expect fun &lt;T&gt; runBlocking(context: CoroutineContext = EmptyCoroutineContext, block: suspend CoroutineScope.() -&gt; T): T`

I tried someting like:
```var result: T? = null
val job = GlobalScope.launch { result = block }
while (!job.isCompleted) {}
return result!!```
Yeah, I know it has many mistakes, but the main problem is the while loop block the execution of the coroutine.

But this works only for tests

Js runtime is non-blocking by design. Nodejs just kinda hacks it with their sync io apis
