Hmm why would

fun main(args: Array<String>) {
println("Hello World!")
println(JSON.plain.stringify(Foo("Hey")))
}

data class Foo(val foo: String)

throw a ClassCastException: Illegal cast? I'm using Kotlin-JS, so I don't have a stacktrace.

You forgot to apply @Serializable annotation on your class
