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.
Example
This example shows the different ways of declaring Boolean variables.
package main
import ("fmt")
func main() {
var b1 bool = true
var b2 = true //untyped declaration
var b3 bool //declaration without initial value
b4 := true //untyped declaration
fmt.Println(b1) // Outputs true
fmt.Println(b2) // Outputs true
fmt.Println(b3) // Outputs false
fmt.Println(bo4) // Outputs true
}

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