This lesson discusses pointers and how to pass them as arguments in GO

We'll cover the following

Go and Pointers

Go has pointers, but no pointer arithmetic. Struct fields can be accessed through a struct pointer. The indirection through the pointer is transparent (you can directly call fields and methods on a pointer).

Note that by default Go passes arguments by value (copying the arguments), if you want to pass the arguments by reference, you need to pass pointers (or use a structure using reference values like slices and maps.

To get the pointer of a value, use the & symbol in front of the value; to dereference a pointer, use the * symbol.

Methods are often defined on pointers and not values (although they can be defined on both), so you will often store a pointer in a variable as in the example below:
