An experiment in development tool fitting

For a presentation I built around how learning new programming languages can help you develop new skills and framings for problems, I ended up building a simple app but with four different languages and frameworks.

The app/service is extremely trivial, around scheduling whose turn it is to run a standup for a small agile team, but its purpose is to be interesting enough to be illustrative while also fading away from the foreground to examine the parts of its construction more closely.

I chose Javascript for my control and then three experiments in ML-decendent languages that all support a similar set of features but with differing syntaxes and ecosystems

// The code below doesn't care what `logger` is, only that it exports `log`!
// This creates a test seam / interface behind which you can replace it with ANYTHING!
// You only care that the thing being exported has a `log` function!
import { log } from './logger'
