Beginner question

Hey there.

I am still fairly new to Hooks in general and trying to improve and learn so bear with me.
Would the following way of inlining and wrapping the mutate function in my custom useUser hook, have any bad consequence?
It seems to work great, and it makes it really easy to consume my custom hook and handle both GET and POST when authenticating.

export function useUser() {
  const { data, mutate } = useSWR(endpoints.auth)

  return {
    user: data,
    login: (email, password) => mutate(login(email, password)),
  }
}

function login(email, password) {
  return postFormData(endpoints.auth, {
    email,
    password,
  })
}

This way i can do const { user, login } = useUser() and access user and invoke login very easy, but i'm not sure if its bad practice in some way. Maybe creating a lot of anonymous functions on each hook cycle or something?

Thanks in advance!
