I want to loop throught a request

     for (let i = 0; i < req.body.email.length; i++) {
...  = req.body.email[i];
...  = req.body.role[i];
    ..}

The result should look like this:

{
  users: [
    { email: 'a@gmx.de', role: 'read' },
    { email: 'b@gmx.de', role: 'admin' },
    { email: 'c@gmx.de', role: 'read' },
    ...

  ]
}

I tried really long but just cant get it in this format in a simple and clean way. Whats the best and cleanest way to do this?
