I need to use a code in JavaScript to determine a user, I decided to use his session ID. Is it safe if I expose a user’s session ID to himself?
Can he use the ID to hack a website sessions or change them?

He can see the session id anyway by examining the cookies (with cookies disabled it’s usually even appended to every link as a GET argument).
So no, he cannot do anything evil with his own session id.
