Class JSArrays

java.lang.Object
dev.gmitch215.bytebox.js.JSArrays
public final class JSArrays extends Object
Builds a JavaScript array from a Java one.

JSArray.of is the interop's own version of this and it does not survive being reached from a new place: its body is generic, the compiler specialises it per call site, and past some number of specialisations it emits local.set expected type externref, found array.get and the module no longer compiles. The failure lands in whichever method called it, which is a long way from the cause.

Nothing here is generic at the boundary. The two scripts take and return JSObject, so there is one shape to compile however many element types call through.

Since:
1.0.0
