How does automatic memory management work in the garbage collector in Go?

In the Go language, automatic memory management is implemented through a built-in garbage collector (GC). It works on the principle of detecting and freeing unused objects in memory to prevent leaks.

Main features of Go's garbage collector:

• Tracing GC: The collector tracks objects that are referenced and frees those that are no longer accessible.
• Parallel and concurrent: GC runs simultaneously with the program, minimizing pauses.
• Automatic trigger: The collector runs automatically when memory usage reaches certain thresholds.

For example, when an object is created in Go, it is allocated on the heap. If there are no more references to this object after the code executes, the garbage collector will free the memory occupied by it without developer intervention.

Thus, Go frees the developer from manual memory management, reducing errors related to leaks and double freeing.
