is the Atomics namespace object available in Kotlin/JS?

<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics>

I'm not sure (at least I didn't find such declarations inside kotlinx.browser and in kotlin-wrappers).
For now, you could define it by yourself with `external` keyword like this:
```external object Atomics {
   ...
}```

We will support it in Kotlin Wrappers.

Implemented :wink:
Expected in next release (probably tomorrow).

<@U01681FLZC2> Do you need `Atomics.waitSync` (not supported in Firefox)?

thanks <@U33H6SB2B>! `Atomics.waitSync` would be nice, but it’s not critical

Do you have examples how you will use `Atomics.waitSync` ?

not yet, I’m still experimenting. But `Atomics.wait` doesn’t work on the main thread, only in web workers. So if I wanted to wait for a web worker to complete on a main thread I’d have to use a SharedArrayBuffer and `Atomics.waitSync`

or, that’s what I understand, I’m not 100% sure, and maybe there’s an alternative

Firefox support isn’t required? :neutral_face:

at the moment I’m just writing a test utility, so I can control the browser I use to test

Firefox support would be nice but I think that’s out of our control :)

Issue - <https://github.com/JetBrains/kotlin-wrappers/issues/2073>

<@U33H6SB2B> does the Kotlin Wrappers project have opt-in annotations for browser specific functionality? E.g. `Atomics.waitAsync` could be annotated with `@LimitedBrowserSupport` (or something similar)?

We use similar strategy with TS declarations - supported in 2 main browsers (like in case of `Atomics`)

Release for `Atomics.waitAsync` requested

For result checks you can use `is/as` operators
`WaitResult` children are classes
