Replacing part of the string

Another very common task related to string processing is the replacement of the substring in a string. Go standard library provide the Replace function and Replacer type for the replacement of multiple strings at once.

How to do it...

1. Open the console and create the folder chapter02/recipe06.
2. Navigate to the directory.
3. Create the replace.go file with the following content:

        package main

        import (
         "fmt"
         "strings"
        )

        const refString = "Mary had a little lamb"
        const refStringTwo = "lamb lamb lamb lamb"

        func main() {
          out := strings.Replace(refString, "lamb", "wolf", -1)
   ...
