It is not correct to assume that arg0 has been generated to have the same IrType as the whole expression. The reason it only backfired in throwing exceptions probably has to do with the fact that visitThrow might be the only place in ExpressionCodegen right now which uses the IrType from PromisedValue to make a decision on whether to generate checkcast. It seems suspicious that ExpressionCodegen.visitFieldAccess/visitCall return PromisedValue whose IrType mentions type parameters which are declared outside of the call site, but that should probably be investigated separately. #KT-48440 Fixed
JavaScript Translation
This module performs the translation of Kotlin source code to JavaScript.
There are various Kotlin APIs to JavaScript environments in the standard library.
Compiling the Kotlin Standard Library for JavaScript
The Kotlin Standard Library for JS is built with gradle, see the corresponding module's ReadMe.
Reusing JVM based test cases in JavaScript
Any Kotlin test cases using the org.junit.Test annotation and the kotlin.test package, such as this test case are automatically converted to JavaScript using QUnit.
This allows the test cases to be run directly in a web page in any web browser.
Using the Kotlin Library in JavaScript
There is a simple sample which shows how to use the Kotlin Standard Library from inside JavaScript in a web page.
