 - Allows us to use more functions to operate on one variable.
 - Low cost by passing memory addresses (8 bytes), copy is not an efficient way, both in terms of time and space, to pass variables.
-- `string`, `slice` and `map` are reference types, so they use pointers when passing to functions by default. (Attention: If you need to change the length of `slice`, you have to pass pointers explicitly)
