Care to elaborate? There are some nifty tricks when it comes to golfing JS.

Well sorry I was in a hurry when I typed the above comment

Well the body can’t have any dom elements according to the challenger

That means I had to create the dom elements as well and I was unable to figure out a way within the given character limit

I wonder if document.write() would work for you. The old-fashioned APIs from before the DOM era (e.g innerHTML, innerText) generally seem to be a lot shorter although they're still a bit verbose.

Yes I guess that was the right way all along, I saw a comment on this thread using innerHtml and write

JS is ok, it’s the DOM APIs that are verbose. I mean this is just to handle the enter key:

    f.addEventListener('keypress',e=>{if(e.keyCode==000) etc()})

Just a fun note: You can replace this

    f.addEventListener('keypress',e=>{...})

With the older but essentially equivalent

    f.onkeypress=e=>{...}

and save 18 characters. You can even use `onkeyup` and save 3 more characters.

Exactly these were the challenges I faced when using plain js
