Answer 1

Utkarsh Bansal place your javascript code inside the following function

onload=()=>{

}

the above function will only run when html document if fully loaded unlike what is happening in your case is that javascript is getting executed before dom loading ,which means the element body doesn't exist yet.

And this is happening since sololearn puts js file inside head tag.
