Parallelism

Google's Jake Archibald make excellent points in the Async functions document about not getting too sequential with your awaits. The idea is to avoid stacking awaits, when possible, and instead trigger tasks immediately and use await after said tasks are triggered:

Parallelism.js

// Will take 1000ms total!
async function series() {
  await wait(500);
  await wait(500);
  return "done!";
}

// Would take only 500ms total!
async function parallel() {
  const wait1 = wait(500);
  const wait2 = wait(500);
  await wait1;
  await wait2;
  return "done!";
}
