String

Go comes with a string type as well as a strings package with a suite of useful functions such as Contains(), Join(), Replace(), Split(), Trim(), and ToUpper(). There is additionally a strconv package dedicated to converting various data types to and from strings. You can read more about the strings package at https://golang.org/pkg/strings/, and the strconv package at https://golang.org/pkg/strconv/.

Double quotes are used for strings. Single quotes are used only for an individual character or runes, not strings. Strings can be defined using the long form or short form with the declare-and-assign operator. You can also use the ` (backticks) symbol to encapsulate strings that span multiple lines. Here is a short example of string usage:

package main

import "fmt"

func main() {
   // Long form assignment
   var myText = "test string 1"

   // Short form assignment
   myText2 := "test string 2"

  
   // Multiline string
   myText3 := `long string
   spanning multiple
   lines` 

   fmt.Println(myText) 
   fmt.Println(myText2) 
   fmt.Println(myText3)
}
