- In-depth analysis of design patterns in golang framework
- Design patterns are widely used in the Go framework to improve code flexibility and maintainability. Specific design patterns include: Singleton pattern: ensures that a class has only one instance; Observer pattern: allows objects to subscribe to and respond to events; Factory method pattern: provides an interface to create objects, and the subclass determines the specific creation of the class.

- How does the golang framework compare with other language frameworks?
- The Go framework is popular for its parallelism, simplicity, and performance. Compared with other language frameworks, it provides various features, such as lightweight Web frameworks (Echo, Gin), high-performance Web frameworks (Iris, Negroni), full-stack frameworks (Beego), MVC-based frameworks (Revel ) and a modern web framework (Buffalo). In actual combat, we used the Gin framework to build a simple blog application, demonstrating the Go framework's ability to create article lists, article details, and article creation forms.

- How does Go WebSocket implement message queue?
- GoWebSocket implements message queues by using channels. The implementation steps are as follows: 1. Create a message queue channel. 2. Start a goroutine to listen for incoming messages. 3. In the handler, write the message to the message queue. 4. When a message needs to be sent, write the message to the queue. This approach can be used to build real-time applications such as chat, collaborative editors, and real-time stock updates.

- How to create immutable custom types in Golang?
- Yes, creating immutable custom types in Go provides many benefits, including thread safety, ease of reasoning, and stronger error handling. To create an immutable type, you need to follow the following steps: Define the type: Declare a custom type that contains member variables and should not include pointers. Declare immutability: Make sure all member variables are base types or other immutable types and avoid using slices, maps, or pointers. Use value receiver methods: Use value receivers for methods associated with a type, disallowing structure literal allocation, and forcing methods to operate only on themselves.

- How does the golang framework architecture achieve high concurrency processing?
- In the Go framework architecture, the key strategies to improve high concurrency processing capabilities are: utilizing the lightweight concurrency mechanism of Goroutine to execute tasks in parallel and improve CPU utilization. Use concurrent channels for safe and efficient data exchange between coroutines to ensure data consistency and concurrency. Implement an asynchronous processing mechanism to move time-consuming tasks to the background for execution to avoid blocking request responses and improve response capabilities.

- How to overload operators for custom types in Golang?
- In Go, you can customize types by overloading operators by creating a method with the same name for the type, receiving another type instance and returning the same type of result. This way, custom operators can be used just like built-in operators, thus facilitating code ease of use and readability.
