Please help me understand what I'm missing

Hey there,

I’ve been working on an assignment from the React course I’m taking, one of the tasks asks you to logout the user when he gets a 401 status code and reload the page.

function client(
  endpoint,
  {data, token, headers: customHeaders, ...customConfig} = {},
) {
  const config = {
    method: data ? 'POST' : 'GET',
    body: data ? JSON.stringify(data) : undefined,
    headers: {
      Authorization: token ? `Bearer ${token}` : undefined,
      'Content-Type': data ? 'application/json' : undefined,
      ...customHeaders,
    },
    ...customConfig,
  }

  return window.fetch(`${apiURL}/${endpoint}`, config).then(async response => {
    if (response.status === 401) {
      await auth.logout()
      // refresh the page for them
      window.location.assign(window.location)
      return Promise.reject({message: 'Please re-authenticate.'})
    }
    const data = await response.json()
    if (response.ok) {
      return data
    } else {
      return Promise.reject(data)
    }
  })
}

My question is about this part from their solution :

 if (response.status === 401) {
      await auth.logout() // deletes token from local storage
      // refresh the page for them
      window.location.assign(window.location)
      return Promise.reject({message: 'Please re-authenticate.'})
    }

if window.location.assign(window.location) is executed, won’t that refresh the page, meaning that the function will never get to that last return statement?
or am I missing something?

Any help would be appreciated :pray:
