Pointers in Go?

Question

go

For a very long time I tried to delve into pointers in Go and in general in general, but did not understand the principle of their work. Can you explain with simple examples or metaphors?

Answer 1

Your grandmother knows where Aunt Galya lives. In fact, your grandmother has a pointer to Aunt Galya in her RAM. Dereference pointer to Aunt Galya = visit her at her address.
You know where your grandmother lives. And grandmother - where is Aunt Galya. You have a pointer to your grandmother. Double dereferencing = go to your grandmother and ask her for the address of Aunt Galya, and then come to visit her.
