Hello. I'm running a Ktor server with a particular endpoint that responds a CommonDateTime class object. In a kotlin,js client, I'm making a fetch request to the endpoint and I'm trying to parse the JSON to CommonDateTime class like this:
```it.json().await().unsafeCast&lt;CommonDateTime&gt;()```
CommonDateTime:
```expect class CommonDateTime(millis: Long) {
    fun getYear(): Int
}```
However, calling `getYear()` function on a casted instance yields an error: `TypeError: is not a function` (since `unsafeCast` just uses dynamic JS values). Is there an alternative to `unsafeCast` that would actually create the objects from JSON so that I could call its instance methods?

You can use `kotlinx.serialization` to receive Kotlin/JS class instance from JSON or JS object

Maybe it will be useful
There is some problems with ktor + DCE, which will be unactual in 1.4-M2
