003: Pointers or !Pointers, stack, and heap
Update: 2022-02-03
Description
We go over what are pointers and when to use or not use them. For instance, this is probably not a good use for pointers.
func main() {
var i int = 10
abc(&i)
}
func abc(i *int) {
*i = 15
}
In my opinion any dereferencing is probably bad. Better way:
func main() {
var i int = 10
i = abc(i)
}
func abc(i int) int {
return 15
}
I also try to give some basics info regarding the stack and heap and why pointers might not be seen as an optimization.
I have a course on building SaaS in Go.
