test VS elm-architecture-tutorial

The de-facto standard for testing an Elm application is elm-test. However, as noted in the README:

Once all that handwritten C code was solid, I needed to make sure the C generated from Elm was working properly. I found the source for the core library's unit tests and decided to port them into my project and add some of my own tests. You can run the tests in WebAssembly in your browser too. (Funnily enough, one of the biggest challenges was getting the Elm Test framework itself to run! The framework is more complex than the tests themselves. I still need to come back to the fuzzer tests!)

Lesson Learned: Elm has built in recursion improvements for a variety of positive reasons, and you should think in recursion to solve looping problems. Use property/fuzz tests and bounds checking with early exit to prevent this from locking up your UI (i.e if > 9000, omg abort). If you’re algorithm is reasonable, but the data set is just gigantic, offload to a server instead for more horsepower. Or Workers if you don’t have server chops, can’t upload the large data, or don’t trust your server devs. (“But Doc, I’m the server dev!” Good joke. Ever̸y̴b̸ody laugh. Roll on s̵͓̆nâ̶̱re drum. Curtains.)

I'm learning Haskell right now, pure functional language, but if anyone is interested, Elm is based on Haskell and much easier to learn. Elm is a web development language that compiles to JS. https://guide.elm-lang.org/

Elm is a different approach that compiles into JavaScript. In the extreme case, you have Emscripten which will compile many language into JavaScript but will feel really clumsy compared to using JavaScript in a lot of cases.

And if you want to stay in the UI realm, Elm is a good introduction into functional programming.

If you want to get better at data structures you should strongly consider learning a functional language. A huge part of functional programming is manipulating data structures. The language Elm is a great place to start for you since it's frontend specific. For example, check out the doc page for the Dict data type and see if that kind of stuff is what you're looking for.

https://guide.elm-lang.org/ for a high level guide, and an unstyled button example https://elm-lang.org/examples/buttons.

I hope this tiny guide was helpful, and that you learned something new today. If you want to learn more about Elm, you should check out the official guide or say hello in the Elm Slack #beginners channel

https://guide.elm-lang.org/ is always a solid example for me

After going through the whole Introductory Guide to the Elm Language and reading the Elm in Action book, I already felt quite comfortable developing webapps in this paradigm. I liked Elm so much that I started a project to teach programming to beginners using this language and made the first classes available on the website elm.dev.br (in Brazilian Portuguese).
