 This is a polyglot Helidon HTTP web service that demonstrates how multiple JavaScript `Context`s can be executed in parallel to handle asynchronous operations with [Helidon](https://helidon.io/), mixing JavaScript `Promise` and Java `CompletableFuture` objects.

 This is a sample application that, for brevity, contains reasonably large snippets of code inside the strings.
 This is not the best approach for structuring polyglot apps, but the easiest to show in a compact way.
