Garbage Collection
Garbage collector is a subsystem of the interpreter that handles de-allocation of memory that is not needed by the program anymore. Garbage collectors can naturally assist interpreted languages, because there is an interpreter. Go is a compiled language, but is different in this respect: it does have garbage collection built into it, even if it does not come with an interpreter.
The Go compiler decides where a variable is allocated: on the stack or on the heap, and it will be garbage-collected correctly.
GC can be invoked programmatically:
runtime.GC()
As of Go 1.8, garbage collection pauses are generally between 10 and 100 microseconds.
API
var s runtime.MemStats
runtime.ReadMemStats(&s)
fmt.Printf("%v\n", s.Sys)
