It is possible to transform a regular Kotlin object into a JavaScript anonymous object using JavaScript's Object.assign(). This allows you to stay in pure Kotlin and in type-safety as long as possible. So:

fun Any.toJsObject(): dynamic {
    val thisArg = this                       // Allows use in js() function
    return js("Object.assign({},thisArg)")
}

val anObject = object { val a = "a" }        // Or use a regular class
console.log( anObject.toJsObject().a )       // logs "a"
