With the popularity and continuous development of the Golang language, more and more developers are beginning to notice its excellent features and the convenience it can bring. In Golang, a method returning an object is a common pattern, and this article will introduce its related knowledge.
What is the object returned by the method?
In Golang, we can represent an abstract concept by defining a structure. Structures can contain variables of different types, as well as the methods they execute. Each method performs a specific task and returns an object or value as a result. When a method returns an object, it actually returns an object of pointer type, which means that it returns the address of the object, not the object itself. The advantage of this is that it can reduce memory usage and make it easier to manage the object's life cycle.

Notes on methods returning objects
When using methods to return objects, we need to pay attention to the following issues:
Sample code
The following is a sample code that defines a Worker structure whose method returns a pointer to an int type.
type Worker struct { id int } func (w *Worker) processJob() *int { // do something return &w.id }
In this example, we define a Worker structure, which has an id member variable, and its processJob method returns an integer of pointer type. In this method, we can process the data stored in the Worker object and then return the address of the object.
If you want to learn more about the methods returning objects in Golang, you can refer to the relevant chapters of the Golang official documentation, and you can also find more resources on the Internet. In short, using methods to return objects can significantly improve the performance and flexibility of your program, and make your code easier to maintain and manage.
