Golang has no objects?

Golang is a very powerful programming language with many advantages such as efficiency, concurrency, and security. Among many programming languages, Golang's design philosophy is famous for its simplicity, which also allows Golang to play a great role in many scenarios.

However, in Golang, you may find a feature that is different from other programming languages-it does not have objects (Object). So, does Golang have no objects? This issue requires further discussion.

First of all, it should be noted that although Golang does not have concepts like "class" and "object" in traditional object-oriented languages, it does provide struct (structure). The structure type is a composite type in Golang, similar to the structure in C language. A structure can contain multiple fields, and each field can be of any type, including other structure types. Because structures can be nested and support anonymous fields, very complex data structures can be implemented.

In addition, Golang is also a language that supports object-oriented programming. Although its implementation is different from other languages, there are still many object-oriented programming ideas and techniques.

For example, functions in Golang can have receivers to simulate methods. A receiver is similar to the this or self keywords of methods in other languages, that is, it points to the object on which the method is currently called. Using receivers allows you to convert Golang functions into methods, making it a form of object-oriented programming.

In fact, defining methods in a receiver manner makes Golang more suitable for object-oriented programming. In this way, function members can access the object it is called on and its members. Compared with explicit this or self in traditional object-oriented languages, this approach can bring higher code readability and simplicity.

In addition, in Golang, inheritance can be simulated through composition, which is also a form of object-oriented programming.

To sum up, although Golang does not have explicit objects, you can still use object-oriented programming using structures and function receivers. Golang's design philosophy is to "keep it simple" and achieve the most powerful programming capabilities through the simplest possible design. Moreover, Golang's design philosophy has also promoted the syntax design of many other languages ​​based on this, becoming a very practical value language.

In actual development, you can choose to use object-oriented methods or other methods to design programs according to specific requirements and scenarios. Choosing the most appropriate method is something that programmers need to consider and consider. All in all, although Golang does not have objects in the traditional sense, it has a unique design concept and implementation method when implementing object-oriented programming, which is more flexible and simple.
