Here, we have used the > comparison operator to check whether a (whose value is 3) is greater than b (whose value is 2). Since 3 is greater than 2, we get true as output.

In this tutorial, you will learn how to use JavaScript logical operators including logical NOT (!) AND (&&), and OR (|) operators.
