To provide the right type, use JSValue(globalObject->functionPrototype()).

In this formulation we have the right type but the compiler doesn't know it. So, you need to #include FunctionPrototype.h.
We shouldn't use this formulation, though, unless we can guarantee that the target callee in fact has a [[Prototype]]. I don't think we can guarantee that.</pre>
