// The Async/Await section spreads some misinformation and bad practices. It explains that try/catch must be used whenever an await expression is used, but that is not the case. For example, this snippet:

function getGithubUser(username) {
  return new Promise((resolve, reject) => {
    fetch(`https://api.github.com/users/${username}`)
      .then(response => {
        const user = response.json();
