Mastering JavaScript: Easily Change Display Visibility and Update Boolean Values On Click

In web development, interactivity is key. If you want to create a dynamic user experience, knowing how to manipulate elements on your page is essential. One common challenge you might encounter is how to change display visibility and boolean values when a user clicks a button. If you've ever been stuck trying to make those changes in JavaScript, don’t worry. You're not alone! Let’s break down a common issue and learn how to solve it.

The Problem

Imagine you have a scenario where two views (or elements) need to be toggled when a button is clicked. At first, one view is displayed, and the other is hidden.

In your JavaScript code, you may find that the desired changes aren't happening even though everything looks correct on the surface.
