How to use CDN-JS library in TS-script on jsfiddle.net platform?

Question

For example, I have sfiddle-example-js script like this and it works:

const { parallelLimit } = async

new Promise(async () => {
  const tasks = Array(10)
    .fill(null)
    .map((item, i) => async () => i)
  const limit = 5
  await parallelLimit(tasks, limit)
    .then((results) => console.log(results.join(',')))
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/async/3.2.3/async.js"></script>

But when I switch it to TypeScript, this script doesn't work.

Now I have to do something like this,

npm i --save-dev @types/async

but how do I do it in the https://jsfiddle.net platform?
