Why is my code printing it out multiple times?

Can someone please explain why code is printing out the message multiple times? It doesn't make sense to me.

The "+=" operator adds on to a string, leaving what was there before. So each time through the loop, the current record is added to the end of everything that was written before, and then the whole thing is output again.

Moving the "let html = '';" statement inside the loop will allow it to start fresh each time, and output each student record only once.

Legend! It totally helps to get a second pair of eyes, I completely missed that. Thanks once again, Steven!
