示例1: throwVMTypeError
static EncodedJSValue JSC_HOST_CALL constructPromise(ExecState* exec)
{
JSGlobalObject* globalObject = exec->callee()->globalObject();
VM& vm = exec->vm();
JSValue newTarget = exec->newTarget();
if (!newTarget || newTarget.isUndefined())
return throwVMTypeError(exec);
JSPromise* promise = JSPromise::create(vm, globalObject->promiseStructure());
if (!jsDynamicCast<JSPromiseConstructor*>(newTarget)) {
JSValue proto = asObject(newTarget)->getDirect(vm, vm.propertyNames->prototype);
asObject(promise)->setPrototypeWithCycleCheck(exec, proto);
}
promise->initialize(exec, globalObject, exec->argument(0));
return JSValue::encode(promise);
