I have encountered and a related problem, which may well have been the same thing. When I tried to produce a `BrowserProductionRun`, the resulting JavaScript files lacked any references to anything but the `main()` function.

I am writing a JavaScript library that I want to call from an HTML file, so I have a number of functions that aren’t called within the module itself, but will be called from JavaScript. Unfortunately, Kotlin’s Dead Code Elimination was eliminating those functions. As per [this page](https://kotlinlang.org/docs/reference/javascript-dce.html), simply adding

```
dceTask {
   keep("myModule.myFunction")
}

```

to `build.gradle.kts` did the trick.

Is this the only way to prevent the compiler from eliminating functions it thinks are pointless?
