Booleans

Booleans are values that can be either true or false.

Basic usage

let myBoolean = true
let myBoolean: Boolean = true
let isEnabled: Boolean = false

let age = 21
let isAdult = age >= 18

let temperature = 32
let isFreezing = temperature <= 32

let isLoggedIn = true

if isLoggedIn {
	console.log("Welcome back")
}

You can either use not or no to negate a value.

let hasAccess = false

if not hasAccess {
	console.log("Access denied")
}

if no hasAccess {
	console.log("Access denied")
}

function isPositive = (value: Integer): Boolean => value > 0

isPositive(12) -- true
isPositive(-3) -- false

let featureFlags = {
	debug = true
	telemetry = false
}
