Exploring JavaScript Logical OR Operator

Introduction

In this lab, we will explore the logical or (||) operator in JavaScript. The purpose of this lab is to understand how the logical or operator works and how it can be used to check if at least one of the given arguments is true. Through practical examples, we will learn how to implement the logical or operator in our code.

Using the Logical OR Operator in JavaScript

To begin coding practice, open the Terminal/SSH and enter node. The logical OR operator (||) checks if at least one of the given arguments is true.

Here's an example of using the logical OR operator:

const or = (a, b) => a || b;

And here are some examples of the output when using the operator:

or(true, true); // true
or(true, false); // true
or(false, false); // false
