Why won't my content display before the second alert, even though the script is just before the closing <body> tag?

Near the end of the video, Guil moves the script for the second alert near the bottom of the page, just before the closing <body> tag. This results in the html content being displayed before the second alert.

This didn't work for me, does anyone know why? I am using Chrome.

I managed to get it to work by using a (complicated looking....to me) window.addEventListener event that I found on google, but I'd love to know why it didn't work like in the video.

Thanks!

It's probably due to a difference in the behavior of browsers when the video was made. Modern ones defer rendering of the page until after all the JavaScript code has finished running.
