Boolean), then the method is no longer created. In short, the method usesFlag (_initialized) to determine if any method has been given to the prototype. This method is created and assigned only once, and traditional OOP developers are happy to sendNow, this code looks more like a class definition in other languages.What kind of approach should we adopt?as mentioned earlier, the most widely used is the hybrid constructor/prototype approach.
