TypeToken.isAssignableFrom() difference on JS and JVM platforms #7

Closed NorbertSandor closed 1 year ago

NorbertSandor commented 1 year ago

I'm experimenting with this library and the

generic<Collection<Int>>().isAssignableFrom(generic<List<Int>>())

expression gives different results on JS and JVM:

JS: false JVM: true

Is this expected behaviour?

(I tried with 2.1.0 because I'm stuck at Kotlin 1.7.10.)

Sorry for the late response. It is totally expected as for JS there is no class hierarchy, thus Collection is absolutely not a super class of List. This behaviour is also expected for Native targets as reflection is really limited outside of the JVM scope.
