Boolean Data Type

We use the typeof operator to check the data type of variables, for example.

1234
let isRaining = true; console.log(typeof isRaining); // or like this console.log(typeof(isRaining));
copy

As you can see in the above code we declared a variable named isRaining with the value of true, and its data type is boolean as expected.
