void myFunction(const FunctionCallbackInfo& args) { if (args.Length() < 2) { // Throw an exception if the function was called with fewer than 2 arguments isolate->ThrowException(Exception::TypeError(String::NewFromUtf8(isolate, "Wrong number of arguments"))); return; } // Do something with the arguments }
void myFunction(const FunctionCallbackInfoIn this example, we define a function called `myFunction` that takes in a `FunctionCallbackInfo` object as its argument. We then use a `for` loop to iterate over all the arguments that were passed to the function. Package/library: V8 engine Overall, V8 Arguments Length is a useful feature of the V8 engine that allows developers to work with the arguments that are passed to a function in a flexible way.& args) { for (int i = 0; i < args.Length(); i++) { // Do something with each argument } }
