Jane Street OCaml Challenge: Hello World

Welcome to Jane Street's OCaml challenges! This exercise is just meant to familiarize you with the system.

Write OCaml code using your favorite text editor; if you aren't already committed to one, we recommend Visual Studio Code.

To compile your code and run inline tests, run:

dune runtest

Try building this code.

You should see a compilation error because it's missing the end quote. Add the end quote and re-run. You should see that the code compiled and ran!

You can also execute code in utop directly. Try pasting this line of code into utop and running it there:

let () = Stdio.printf "Hello, World!"
