Overview

strings package of GO provides a ReplaceAll method that can be used to replace all non-overlapping instances of a given substring with a new substring. We can use this method to delete a substring by providing the replacement of the substring to be deleted as an empty string

Below is the signature of the function. The function will replace all non-overlapping instances of old with new in string s. To delete a substring we can supply that substring as old and new as an empty string

func ReplaceAll(s, old, new string) string

Let’s look at the working code

Code:

package main
import (
"fmt"
"strings"
)
func main() {
res = strings.ReplaceAll("abcabcabcdef", "ab", "")
fmt.Println(res)
}

Output:

cccdef
