Introduction For basic syntax, functional programming does not feel that different from other paradigms. Sure, data and behaviour are separate, so you don’t have classes or objects or inheritance, but it feels relatively the same. This is especially true in Rescript, with the pipe-first syntax almost looking like a method lookup (comparable to the self object in Python). But if you go deeply into a study of functional languages, you start encountering bizarre words such as “monad” and “functor”.
In a recent article I introduced rescript-zora, a library I wrote for unit testing Rescript code with lightning fast responses. One drawback of zora is that it’s very minimal. In this article, I explore some design principles and go on a bit of a rant about the definition of the word “unit”.
I wrote Rescript bindings to the zora test framework and wanted to write about how to actually use them.
