Javascript Boolean doesn't work, Larvel 5.6

I want to redirect the user to the edit.blade page when they login for the first time. for this I made an if else statement, but it doesn't work and i have no idea what the problem is. Can someone help me.

this is the code that i have now:

 // This section is the only change
    if ($this->guard()->validate($this->credentials($request))) {
        $user = $this->guard()->getLastAttempted();
        dd($user);
        // Make sure the user is active
        if ($user->verified && $this->attemptLogin($request)) {


            if ($user->first_time_login == true || $user->first_time_login == 1) {
                $this->redirectTo = '/users/edit';
                $user->first_time_login = false;
                $user->save();

            }

            return $this->sendLoginResponse($request);
