Asynchronous output and queue priorities

Perform a code review: investigate the order of execution and priorities of tasks (macrotask vs microtask).

setTimeout(() => {
  console.log('timeout 0');
});

Promise.resolve()
  .then(() => {
    console.log('promise foo');
  })
  .then(() => {
    console.log('promise bar');
  });

const promise = new Promise((resolve, reject) => {
  console.log('promise baz');
  resolve(true);
});

promise.then(() => {
  console.log('promise fez');
});

console.log('initial flow');
