Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

My efforts to port http://www.youtube.com/watch?v=f6kdp27TYZs to Clojure.

A boring function (6:22)

func boring(msg string) {
  for i := 0; ; i++ {
    fmt.Println(msg, i)
    time.Sleep(time.Second)

// USAGE

const queue = new Queue(50)
const middleware = () => async (ctx, next: () => Promise<void>) => {
    const lock = await queue.take()
    await next().finally(() => {
        queue.release(lock)
    })
}

Copy this into the console of any web page that is interactive and doesn't
do hard reloads. You will hear your DOM changes as different pitches of
audio.

I have found this interesting for debugging, but also fun to hear web pages
render like UIs do in movies.

Elm quickstart with Parcel

Create project boilerplate:

mkdir my-elm-project
cd my-elm-project
elm init
touch src/Main.elm # This is where we put our Elm app
