Go interface{} vs any
Article Introduction：In Go language, interface{} and any are exactly the same type. Since Go1.18, any has been introduced as an alias for interface{}. The main purpose is to improve the readability and semantic clarity of the code; 1. Any is more suitable for scenarios that express "arbitrary types", such as function parameters, map/slice element types, general logic implementations, etc.; 2. Interface{} is more suitable for defining interface behavior, emphasizing interface types, or compatible with old code; 3. The performance of the two is exactly the same as the underlying mechanism, and the compiler will replace any with interface{}, which will not cause additional overhead; 4. Pay attention to type safety issues when using it, and may need to cooperate with type assertions or

How do I define an interface type in Go?
Article Introduction：In Go language, interfaces are defined through interface keywords, and their core is the method set; 1. The interface definition uses the type interface name interface{method signature} form, such as the Animal interface contains the Speak()string method; 2. The type implicitly satisfies the interface through the implementation of the interface method, without explicit declaration; 3. The empty interface Anyinterface{} can receive any type and is often used for general parameter processing; 4. The interface can form a more complex abstraction by nesting and combining multiple interface behaviors.
