Golang : Join arrays or slices example

A quick note on how to join arrays or slices in Golang. So used to Python way of joining arrays with + symbol. However, it is not available in Golang :(

To join two arrays in Golang, use the append function instead.

 package main

 import (
 "fmt"
 )

 func main() {
 list1 := []int{1, 2, 3}
 list2 := []int{4, 5, 6}

 // python way - will not work in Golang
 //list3 := list1 + list2
 //fmt.Println(list3)

 list3 := list1

 // example
 // to combine two slices or join arrays, use for loop and builtin append function
 for index, _ := range list2 {
 list3 = append(list3, list2[index])
 }

 fmt.Println(list3)

 // another example
 // super quick way to join arrays
 fmt.Println(append(list1, list2...))

 }

Output:

[1 2 3 4 5 6]

[1 2 3 4 5 6]
