Strings

In Go, strings are sequences of Unicode characters, which essentially means they represent textual data. String data is always enclosed in double quotation marks (") or backticks. The string data type is represented by the string keyword.

go

index

copy
var myString string = "Hello World"

              
1

            
var myString string = "Hello World"

Note

A string is a data type in Go, while a string literal refers to the actual representation of a string value within the source code, for example, Hello World.

We can write a string literal in multiple lines by enclosing it in backticks (``). You can see the difference in the following program:

go

index

copy
package main
import "fmt"

func main() {
var myString string
// Using double quotes ("")
myString = "Hello World"
fmt.Println(myString)
// Using backticks (``)
myString = `Hello World`
fmt.Println(myString)
}

              
1234567891011121314

            
package main
import "fmt"

func main() {
    var myString string
   
    // Using double quotes ("")
    myString = "Hello World"
    fmt.Println(myString)
   
    // Using backticks (``)
    myString = `Hello World`
    fmt.Println(myString)
}

Strings can be joined together using the plus (+) operator:

go

index

copy
package main
import "fmt"

func main() {
var stringOne string = "Hello"
var stringTwo string = "World"
var stringThree string = stringOne + " " + stringTwo
fmt.Println(stringThree)
}

              
1234567891011

            
package main
import "fmt"

func main() {
    var stringOne string = "Hello"
    var stringTwo string = "World"
   
    var stringThree string = stringOne + " " + stringTwo
   
    fmt.Println(stringThree)
}

The process of joining two strings using the (+) operator is called string concatenation.
