Basic Understanding of Pointers in Go

gistfile1.go

package main

import "fmt"

// Explanation:
// changeIt() takes as argument a pointer to a thing
// in line 14 we create such a pointer and pass it to changeIt().
// Hadn't we used a pointer but instead passed thing *normally*,
// we would not have been able to observe the change
// from "yolo" to "roflmao" in main

func main() {
	thing := Thing{name: "yolo"}
	changeIt(&thing)
	fmt.Println(thing.name)
}

type Thing struct {
	name string
}

func changeIt(thing *Thing) {
	thing.name = "roflmao"
}
