I don't know if there are actually those words, but this idea is real. By default, any string other than empty string or number other than 0 is treated as truthy value in conditionals. This is also applicable to other datatypes too.<br> <a href="https://res.cloudinary.com/practicaldev/image/fetch/s--31K8mC6O--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/50i3aw2kutk5jwspu05s.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--31K8mC6O--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/50i3aw2kutk5jwspu05s.png" alt="Image description" width="800" height="450"></a></p></li> <li><p>Using square bracket notation [] for accessing object properties is significantly better, at least in my experience as it allows you to dynamically use it, whereas it is not possible with dot notation.</p></li> </ul>
