Code works on JSFiddle but when saved locally doesn't work [duplicate]

问题

I am trying to take in input from the user and display it as a list. Thankfully someone has already done it and found it on JSFiddle. The codes works fine there but when I move it locally, it is not working. When I enter the text, nothing happens. I went through similar issues here but still not working.

Please advice if you spot the mistake. Thank you.

Since your jquery code comes before your html, i think putting it in a $(document).ready() {} or moving it to the end of the body will make it work again.
