is there a docs page explaining the difference between

Double.javaClass // DoubleCompanionObject ?
Double::class.java // java Double ?
Double // kotlin Double ?

and when to use which?

[Shawn]

Double on its own (not used as a type annotation) will refer to Double’s companion object (of which I don’t think there is one)

[Shawn]

Double::class will yield a KClass<Double>

[Shawn]

.javaClass should be used when you need the Java Class<T> of an instantiated object

[Shawn]

Double::class.java should be used when you need a reference to the Class<T> by way of knowing the name of the class

[Shawn]

I don’t believe there is any one particular docs page that explains the differences unfortunately, this is just what I’ve learned by idling in Slack and checking out stackoverflow questions

thanks @Shawn, that's helpful
