What is the difference between composition and inheritance in golang?

The Go language (golang) is a general-purpose programming language designed by Google; it borrows many good ideas from many other languages ​​while avoiding features that lead to complexity and unreliable code.

Go supports multiple paradigms such as procedural, functional and concurrency. Its syntax is traditionally derived from the C language, but it has been significantly modified to improve features such as simplicity and safety.

The difference between golang combination and inheritance

Inheritance in GO language is also realized through combination. The specific difference between the two is as follows:

If If a struct nests another named structure, this pattern is called composition.

If a struct nests another anonymous structure (only the type without a name), then this structure can directly access the methods of the anonymous structure, thus realizing inheritance.

If a struct nests multiple anonymous structures, then this structure can directly access the methods of multiple anonymous structures, thus achieving multiple inheritance.
