time, I think I can do while learning, no big problem.15. If necessary, in the leisure time of work, we can focus on two questions, first, what idioms and patterns are used in the language, and secondly, the compiler/interpreter implementation mechanism for the language.So that the basic part of the language can be said to master, after the database, network or do graphics, can be based on specific needs to engage, find the appropriate mature framewo

. Decoupling To some extent, the dependency interface is not dependent on the implementation, and the effect can be minimized when the implementation class is replaced. Easy to do unit testing In the case of dependent interfaces, unit testing is easier, and using mocks is easier, in TDD, the
