What are the differences between using visibility and display properties in JavaScript and how can they impact the user experience in a web application?

Using the visibility property in JavaScript will hide an element while still taking up space on the page, whereas using the display property will hide an element and collapse the space it occupies. This can impact the user experience in a web application by affecting the layout of the page and how elements are displayed to the user. ```javascript // Using visibility property to hide an element document.getElementById('elementId').style.visibility = 'hidden'; // Using display property to hide an element document.getElementById('elementId').style.display = 'none'; ```
