Answer 1

What kind of cookies are here, where?
Mixed localStorage and sessionStorage.
Store everything in localStorage.
Well, I will write that a bunch of unnecessary variables that are not used.

sessionStorage.setItem('is_reloaded', 'no');
    if(sessionStorage.getItem('is_reloaded') == 'no') { ... }

So you can't write code.
Set a variable, and immediately check it for the value that was assigned.
I think you need to learn.
