but no options available to to unsafe cast json {"key1":"value1", "key2":"value2", "key3":"value3" } into a Kotlin type.

[Rob Murdock]

this wouldn’t be “casting” in a Kotlin JS context persay, and it might be useful to understand how Kotlin objects look from a JS perspective in order to understand why

[Rob Murdock]

when Kotlin compiles to JS, it uses different names for generated members than the plain strings you see in your Kotlin code (unless you’re using the @JsName annotations)

[Rob Murdock]

so force-casting the JS object to be treated like the Kotlin object wouldn’t actually work the way you’d expect - Kotlin code would look for the generated name, and wouldn’t find the member

[Rob Murdock]

depending on what you’re trying to do, there are a lot of good alternatives. One of which is using the Kotlin serialization library to translate between “dynamic” types and Kotlin types

[Rob Murdock]

with Kotlin serialization, you could probably even just parse the dynamic object into a Map<String, Boolean> and get solid results

Described json is Record in Kotlin

[turansky]

Wrapper already exists
Record<String, String> is what you need

good stuff, thank you both!
