Golang : Reclaim memory occupied by make() example

Problem :

You have allocated some memory for buffer via the make() function and you want to reclaim back the occupied memory after done using the buffer. How to do that?

Solution :

For example :

 buffer := make([]byte, 1024)

or

 buffer := make([][]int, row)

to reclaim back the memory, simply do :

 buffer = nil

Golang's garbage collector will automatically free up the memory or you can trigger garbage collection manually as well with runtime/debug.FreeOSMemory()
