Redirect based on members roles

What about just SHUT one function OFF ???

//-------------- USER-INTERFACE -----------------
let roles = [];
    roles[0] = 'Staff';
    roles[1] = 'Client';
    //roles[2] = 'ADMIN';
    //roles[3] = 'USER';
    //roles[4] = 'SUPPORT';
//-------------- USER-INTERFACE -----------------

$w.onReady(function() {  
    let loggedIn = wixUsers.currentUser.loggedIn  
    if (loggedIn) {getRoleAndRedirect();} 
    else {loginUser();} //--> force log-in
});

//the imports....
function getRoleAndRedirect(){
    return wixUsers.currentUser
    .getRoles()
    .then(roles => {
        if(roles.some(role => role.name === roles[0])){
            return wixLocation.to('/page-a');
        }
        if(roles.some(role => role.name === roles[1])){
            return wixLocation.to('/page-b');
        }
        //if other roles or no role:
        //return wixLocation.to('/page-c');
    });
}

function loginUser(){
    wixUsers.propmptLogin()
    .then((user)=> {getRoleAndRedirect();})
    .catch((loginUser)=>{});
}

BTW, it’s the same code written by J.D. (but a little bit modified).
