#includeIn this example, we define a function "myFunction" that takes in arguments using the "Arguments" class. Then, we use Handle IsUndefined to check if the first argument is undefined. If it is, we do something (in this case, nothing). Finally, we return an "Undefined" value using the "Close" method. Overall, the package library associated with this code example is the V8 engine library.using namespace v8; Handle myFunction(const Arguments& args) { HandleScope scope; // Check if first argument is undefined if (args[0]->IsUndefined()) { // Do something } return scope.Close(Undefined()); }
