Does whatever is put inside the title Just help to keep things organized? Or does it show on the page?
It is suppose to show up in the browser tab, but since codecademy uses an iframe, it will not show. If you try on jsbin for example, it will show. Or even better, create a html file using a text-editor.
So no, it is not just to keep things organized, it actually serves a function
The title is what is shown in the browser's tittle page or tab bar. It's important to always include one when making a webpage.
