How can I get a reference to a Kotlin KClass by name when not running on the JVM?

Question

When targeting Javascript and native java.lang.Class.forName() is not available. How can I get a KClass in these environments?

I've deleted my answer because for some reason I've missed the JavaScript part of the question. Sorry for that. — Alexander Udalov

As it said in Kotlin documentation:

At this time, JavaScript does not support the full Kotlin reflection API. The only supported part of the API is the ::class syntax which allows you to refer to the class of an instance, or the class corresponding to the given type. The value of a ::class expression is a stripped-down KClass implementation that only supports the simpleName and isInstance members.

Here's the example:

val a = A()

print(a::class.simpleName)  // Obtains class for an instance; prints "A"
print(A::class.simpleName)  // Obtains class for a type; prints "B"

I didn't test it on Native nor JavaScript version (it does work on the JVM one) but you can just do SomeClass::class. Kotlin docs
