Difference of hello-world contents between repositories

[porcupinenick]

I'm going through the tutorial and I've noticed something interesting:

1. https://github.com/janestreet/install-ocaml/tree/master/01-hello-world
2. https://github.com/janestreet/install-ocaml/tree/9feff66e166b818e9ecac8ec40bc5c56c241364f/01-hello-world

Why do these two repositories contain different coding standards? Are there any significant differences or advantages running ocaml via jbuild compared to dune?

Can you elaborate on what you mean by “coding standards” here?

dune used to be called jbuilder. One difference between the two is that the configuration files (i.e. the files “dune” for dune and “jbuild” for jbuilder) have a different format. Is that what you mean?

You can read more about the migration from jbuilder to dune here:

Sorry for the confusion; I just noticed the difference and thought there may have been different ways of running the tests. Thanks for the link!
