Async Await Sample

gistfile1.js

async function getGithubUser(username) { // promise + await keyword usage allowed
  try { // We handle async function errors with try / catch
    const response = await fetch(`https://api.github.com/users/${username}`); // Execution stops here until fetch promise is fulfilled.
    const user = response.json();
    return user; // equivalent of resolving the getGithubUser promise with user value.
  } catch (err) {
    throw new Error(err); // equivalent of rejecting getGithubUser promise with err value.
  }
}

getGithubUser('americos')
  .then(user => console.log(user))
  .catch(err => console.log(err));
