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]
