Ethernet switches that do not have loop detection

I’m just curious. I was looking at cheap unmanaged Ethernet switches and some of them say No loop end. I had never heard of that. It seems to me (if I understand this correctly) that if a switch does support this the data lights on the switch would blink a different color indicating that cable is in a loop. For people that don’t know what a loop end is. It lets you know that both ends of a particular Ethernet cable are both connected to the switch. If that is not correct, someone please educate me

I think it's a feature that would be built into the device to prevent this. It's not necessarily the same cable connected but the device on the other end connected to the switch twice which would likely slow things down. Someone with more experience can likely explain better.

I'm not a pro but this is the first I've heard the term "loop end". I know that managed switches can use Spanning Tree Protocol and the basic purpose of that is to prevent network overload due to loops. It can also be used to provide redundant/backup links (which would otherwise create a loop).
I guess some unmanaged switches have basic loop prevention but don't go as far as supporting full STP?
