I am not exactly sure why the instructor's HTML auto refreshes. I have to type quit in the prompt dialog for result.

It actually works as in the video, within FireFox (at the time of this post, FF49). Chrome must have changed how it handled infinite loops.

Ah. I see whatcha mean. I definitely learned something new while creating this codepen. So in a while(true) loop, the DOM never gets a chance to update. A workaround, to achieve the desired effect is to call setInterval()

example with jQuery:

<div id='content'></div>

function promptAndInsertContent() {
  var contentToInsert = prompt('Enter in some text yo!');
 //Press Cancel to quit
if(contentToInsert === null) {
//use clearInterval to exit the timer
   clearInterval(timer);
 }
 $('#content').text(contentToInsert);
}

//call the timer every 200 miliseconds
var timer = setInterval(promptAndInsertContent, 200);

It's simply how his loop is constructed. I know the workspace files don't reflect it (as noted in other forum questions) but using a while loop you can update the DOM until "quit" is typed. Feel free to post your code if you need help, or see the related questions in the forum.

Cool thanks for sharing

Same issue... odd that they don't mention it at all in the video. It's confusing.

Don't forget to "Rate the Video" when you finish seeing it before you click the "Continue" button to go to the next course. That way the instructor gets direct feedback so the video can updated & improved. Let him or her know to be more specific & demonstrate on the video what they're doing & describe it in detail verbally. You can view the written transcript, too. It's easy for an instructor to assume you know what they're doing already. You can always stop the video & rewind it to go back to the part you didn't understand the first time. You can do that as many times as you need to do so. It's O.K. to slow down & not rush through the videos. Sometimes you catch the instructor's typographical errors that way, too. Sometimes the instructor corrects them in the video, & sometimes they forget to do so. Most of the time, they correct themselves in the video.
