Javascript fetch JSON with ES7 Async Await

fetch_json.js

async function fetchAsync () {
  // await response of fetch call
  const response = await fetch('https://api.github.com');
  // only proceed once promise is resolved
  const data = await response.json();
  // only proceed once second promise is resolved
  return data;
}

// more concise
async function fetchAsync () {
  // await response of fetch call
  const response = await fetch('https://api.github.com');
  // only proceed once promise is resolved
  return response.json();
  }
