I don't think the GP meant replacing JS with Kotlin, rather they're referring to implementing React Native modules in Kotlin instead of Java, keeping the JS part untouched. (As you may know, React Native modules/components require native implementations before they can be used in JS).

I hope that clears things up a bit!
