JS function

You can inline JavaScript code into your Kotlin code using the js("…") function. This should be used with extreme care.

fun main() {
    js("alert(\"alert from Kotlin!\")") // 1
}

1. Sending a JavaScript alert from a Kotlin function.

fun main(){
  val json = js("{}")               // 1
  json.name = "Jane"                // 2
  json.hobby = "movies"
  println(JSON.stringify(json))     // 3
}

1. Creates a JavaScript object literal. The js(...) function return type is dynamic.
2. Adds some properties by utilizing the dynamic type capabilities.
3. Passes the JSON to JavaScript API.
