> It is similar to what Elm does to represent its output to the HTML Domain Object Model. The reason I wrote MapDiff is that I am planning on writing a library that wraps Erlang’s wxWidgets bindings in a similar way that Elm wraps the HTML DOM, which would allow people to write GUIs in a Functional style (wxWidgets itself is Object-Oriented). Does this sound like a huge undertaking? Yes! Let’s see how far I can get with it 😁…

That would be awesome and is entirely possible! I’d thought about it myself but wrapping to a QT layer instead. ^.^

This library will be useful to me though, I already have my more specialized one currently. 🙂
