It's incorrect to take the first parameter type from the expression itself because it can be nullable if smart casts are used. And if it's nullable, it's mapped to the wrapper type and calling `comparisonOperandType` for it makes no sense. Instead, take the type from the callee function, as it's guaranteed to be mapped to a JVM primitive type. E.g. in `test1` function in the added test, the problem was that the dispatch receiver type of the call expression is `Double?`, which is mapped to `java/lang/Double`, whereas we clearly wanted to obtain the primitive `D` (double) type. #KT-52163 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.
