Boolean 2/4

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));

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.
