My call stack is returning anonymous not the li like in the video

The teachers video shows createLI and form.addEventListener in the callStack tab but for some reason mine is only appearing anonymous why is that? I haven't touched the code in anyway since we've begun the video

I wasn't sure on this either, but did some quick googling and found that if you simply rename the anonymous function, it will come back with that name. For example on line 59, change from:

form.addEventListener('submit', (e) => {

to:

form.addEventListener('submit', function FixAnon(e) {

Now, when you go through the same exercise, the Call Stack will begin with FixAnon, instead of Anonymous.
