There is no quick success in learning , But it can be very technical ! This course combs the key knowledge for you , Restore through classic development scenarios , Clarify the context of the problem , a farewell “ It's good to realize it ”、“ It can't be maintained ” Plight ;“ encapsulation ”、“ asynchronous ”、“ Architecture design ”、“ object-oriented ” Such obscure terms are no longer mysterious , Give Way “ Readability 、 Extensibility 、 Maintainability ” to ground .
