document.title v/s document.querySelector('title')

document.title v/s document.querySelector('title')

when I try to assign a new value, I am able to with document.title, but not with document.querySelector('title').

What can be the reason?

These are different kinds of things. While document.title is a string, document.querySelector("title") is an element.

The equivalent string to document.title would be document.querySelector("title").textContent.

Frequent use helps make it stick in your mind, but even so you can't expect to remember everything. Whenever I forget, I just look up the specs on MDN, like for document.title and for document.querySelector.
