Removing a string from a slice in Go [duplicate]

Answer 1

Here is a function to remove the element at a particular index:

package main

import "fmt"
import "errors"

func main() {
    strings := []string{}
    strings = append(strings, "one")
    strings = append(strings, "two")
    strings = append(strings, "three")
    strings, err := remove(strings, 1)
    if err != nil {
        fmt.Println("Something went wrong : ", err)
    } else {
        fmt.Println(strings)
    }

}

func remove(s []string, index int) ([]string, error) {
    if index >= len(s) {
        return nil, errors.New("Out of Range Error")
    }
    return append(s[:index], s[index+1:]...), nil
}
