The boolean Type

True and false

Booleans have only $2$ possible values: true and false.

let isLoggedIn = true
let hasPermission = false

Booleans come from comparisons:

let age = 25
console.log(age > 18)   // true
console.log(age === 30) // false

You use booleans constantly in conditions. Every if statement evaluates to a boolean to decide which code runs.
