boolean type

Learn boolean for logical values.

What is the boolean type?

The boolean type takes only two values: true or false. It is used to express a two-state condition such as on/off or yes/no.

let aktif: boolean = true;
let silindi: boolean = false;
console.log(aktif);  // true

The values are always written lowercase.

boolean values can be combined with && (and), || (or), ! (not). Comparison results are also boolean.

let acik: boolean = true;
let kil: boolean = false;
console.log(acik && kil);  // false
console.log(5 > 3);  // true

Declare a boolean variable named aktif and assign true. Then print its value with console.log.
