@ludwig-vaan This is great, thanks! It might be nicer to have all the answers in the master branch itself. Let me think about it and merge it in a few days. |

In my very personal opinion, an example answer probably shouldn't use |> given this syntax was not introduced in this tutorial.

I second that... Pipes are missing as a topic in this exercise. Plus its a very important concept.

@adilmas13 @PraveenInvideo Thanks, that makes sense. We're working on a major improvement to the content and will definitely fix this issue in that.

Where did fst and snd come from? Was the discovery of these functions the purpose of this exercise?

We're leaving this PR open for folks who want to see the answers. Many thanks to @ludwig-vaan. We're working on a new iteration of the course. It'll have online interactive exercises with tests, more focus on types and not just FP/recursion, plus topics on real-world development with modules and interfaces. We'll include the answers as hints/solutions in that version. |
Hi,
If you want, you can create a new branch call answer, and use my commit for it.
btw, thanks for your work, it's appreciable to learn ReasonML.
