Go Booleans

How it works

bool contains true or false. Comparisons produce booleans, and && and || combine them with short-circuit evaluation. Go does not treat an integer or a nonempty string as a boolean condition.

Run this Go example

Install Go separately from the official Go downloads and check go version in a new terminal. The reviewed baseline is Go 1.27.3 on Windows amd64; the authored syntax and standard-library APIs require Go 1.22 or newer. Save the complete source below as booleans.go in a learning folder, then run go run booleans.go from that folder. These examples use only the standard library.

Bhylu has no Go browser runner. Apache, MySQL, PHP and the JavaScript or Python playground are not required to run these files. File examples own a temporary directory; HTTP client examples create an ephemeral loopback server and close it. They do not contact an external API.

Download the complete booleans.go · Download all source files with hash checks

For the optional collection download, save download-examples.mjs in a new learning folder and run node download-examples.mjs. A local preview uses node download-examples.mjs http://127.0.0.1:8000/examples/go/. The downloader refuses an existing bhylu-go-examples folder and installs or executes no Go code.

Example

package main

import (
	"fmt"
)

func main() {
	hasCode := true
	isCollected := false
	canOpen := hasCode && !isCollected
	fmt.Println(canOpen, !hasCode)
}

Expected result

true false

! reverses a boolean. The locker may open only while the code is accepted and collection has not already happened. This is a local rule example, not a real authentication system.
