9 min readIn Golang, memory management is automatically handled by the garbage collector (GC) to free up memory that is no longer in use. However, there may be scenarios where you want to manually free memory in Golang.To free memory manually in Golang, you can use the runtime package which provides functions related to memory management.One way to free memory manually is by using the runtime.GC() function. This function explicitly invokes the garbage collector to clean up memory.
