Web rescript is largely based on ocaml, but it follows a functional programming style and has a clear syntax for defining types and patterns. In my opinion, code that is easy to comprehend is highly valuable because, ultimately, its essence lies in its correctness and readability. Loop through each row and column of the pat.
