Hello, Dada!

⚠️ DADA DOESN'T REALLY EXIST. ⚠️

See the About page for more information. Also, you have to pretend that all the code examples are editable and runnable, with live IDE tooltips and so forth. =)

The classic “Hello, World” program in Dada should be quite familiar:

Loading...

When you run this (try it!) it prints:

I have forced myself to contradict myself
in order to avoid conforming to my own taste.
  -- Marcel Duchamp

There are a few interesting things to note:

  • Dada, like JavaScript, is based exclusively on async-await. This means that operations that perform I/O, like print, don't execute immediately. Instead, they return a thunk, which is basically "code waiting to run" (but not running yet). The thunk doesn't execute until you await it by using the .await operation.
  • Strings in Dada can spread over multiple lines. Leading and trailing whitespace is stripped by default, and we also remove any common indentation from each line.
