You have read about exceptions and how to use them. It is time to learn the benefits of using exceptions in your program. Advantage 1: separating rule code from error handling code Exception Handling requires that the detailed work required when an error occurs be separated from the main logic code of the program.

. MicroServices first emphasize the small scale of services and ease of scaling and expansion of services, but this can also lead to fragmentation of services and challenges to personnel management.2. MicroServices are a distributed system, each of which has its own database, although to a certain extent increases the overall reliability of the application, but also inevitably brings a lot of redundant data.3. As the scale of services grows, the number of instances of microservices will grow rap

leading to complex code, very low development efficiency.In fact, for most Web applications, they don't need complex XML to transfer data at all, and XML claims are rarely advantageous in terms of extensibility, and many AJAX applications even return HTML fragments directly to build dynamic Web pages. Returning HTML fragments greatly reduces the complexity of the system compared to returning XML and parsing it, but at the same time lacks some flexibility. The Data Interchange Format JSON provid

This will save memory.Of course, there is no problem with this statement, but in implementation, not only the use of prototype way to achieve this effect, we can def
