Go Boolean Data Type
Boolean Data Type
A boolean data type is declared with the bool
keyword and can only take the values true or
false.
The default value of a boolean data type is
false.
Example
This example shows some different ways to declare Boolean variables:
package main
import ("fmt")
func main() {
var b1 bool = true // typed declaration with initial value
var b2 = true // untyped declaration with initial value
var b3 bool // typed declaration without initial value
b4 := true // untyped declaration with initial value
fmt.Println(b1) // Returns true
fmt.Println(b2) // Returns true
fmt.Println(b3) // Returns false
fmt.Println(b4) // Returns true
}

Note: Boolean values are mostly used for conditional testing which you will learn more about in the Go Conditions chapter.
