How does garbage collection work in Go?

Go uses reference counting to track memory usage.
Go uses a tracing garbage collector.
Go relies on manual memory management.
Go uses a generational garbage collector.

In Go, the garbage collector uses a tracing garbage collection algorithm. It periodically scans the heap to identify and reclaim memory that is no longer reachable or in use by the program. This allows Go developers to focus on writing code without explicitly managing memory deallocation, making it more convenient and safe. Understanding how the garbage collector works is crucial for optimizing memory usage in Go applications.
