Go supports Goroutine, ultra-lightweight threads. In a highly concurrent system, the program can be written in a multi-threaded manner, ensuring that the logic is clear and simple, and can achieve very high performance.

The same thing in C + +, if you use multithreading, it can lead to a lot of context switching overhead in the system thread, and if you use a message-based architecture, you get high efficiency, but the program logic is broken, readability and maintainability are poor.

In addition, Go has the most powerful interface, so you can discard the C + + Inheritance + virtual method coverage of the programming, for complex systems, the former has better maintainability.
