A modern programming language that makes developers happier.

Let say I want to build a Wasm library with Kotlin/Wasm `1.7.20-Beta` that "exports" `fun add(a: Int, b: Int): Int = a + b`. I don't care about JavaScript here, I just want to specify that the generated Wasm should be shipped with this function and everything else removed (tree shaking). I have no `main()` in my project. How should I specify that in my code and/or how my build configuration `kotlin { wasm { binaries.library() } }` should be customized? Is `@JsExport` the way to go for now?

`binaries.executable()` and `@JsExport` would be the way to go for now.

Note that JsExport of some non-primitive types currently requires autogenerated JS glue to function.

Ok thanks, in term of design I would be curious if you may target a `binaries.library()` + `@WasmExport` for that use case or if you have something else in mind. Other languages usually uses keyword instead of `@JsExport` / `@WasmExport` but maybe there is not enough use cases on other platforms to justify such keyword in Kotlin ...
