Detailed Description

Represents the JS function return value.

To unwrap the return value, check whether it is an error or the actual value, and then use std::move:

JsReturnValue result = object->call("method");
if (result) {
    JsValue value = std::move(result).asValue();
    ...
}

The JS function can either return value or throw an exception and this class represents these two possibilities.
