WebGo Boolean Data Types. A boolean data type represents logical entities. It can have two possible values: true or false. We use the bool keyword to create boolean-type variables. For example, package main import "fmt" func main() { var boolTrue bool = true var boolFalse bool = false fmt.Println("The boolean values are", boolTrue, "and", boolFalse) } Webh := handler{is: &[]bool{true}[0]} fmt.Println(*h.is) // Prints true Basically it creates a slice with one bool of value true , indexes its first element and takes its address. No new variable is created, but there is a lot of boilerplate (and backing array will remain in memory until the address to its first element exists).
