Hi! Any idea how I can write this js in Kotlin? :

var map = new H.Map(
{
center: {lat: 40.745390, lng: -74.022917},
zoom: 13.2
});

center is not properly initialized. I tried defining an interface for center (IPoint) and pass an object:IPoint to the constructor but it doesn't work. Tried to implement the interface in a class and still doesn't work. How to I pass a json anonymous object from kotlin to js? Thank you!

Define the argument as type dynamic and use the js() function, e.g. js("{}") to generate the object?

No dynamic please 🙂

[turansky]

external interface Location {
    var lat: Double
    var lng: Double
}

external interface MapOptions {
    var center: Location
    var zoom: Double
}

// your module config
external class Map(options: MapOptions)

fun main() {
    val map = Map(
        options = jsObject {
            center = jsObject { lat = 40.2, lng = -74.1 },
            zoom = 13.2,
        }
    )
}

Wow! jsObject ... kotlin-wrappers, didn't know about it. Thanks a lot Victor!!!

And js {} if you want dynamic as result
