//Most API's will only allow you to fetch on their website.
//This means you couldn't run this code in the console on
// google.com because:
// 1. Google demands the fetch request be from https
// 2. open-notify's API blocks the request outside of their website
fetch('http://api.open-notify.org/astros.json')
