Elm VS purescript

You also wouldn't really be creating your own new programing language. You would be creating something that can run JavaScript by following JavaScript standards and syntax. You might be able to add some non-standard features of your own on top of those standards, or include your own standard library of helpers or utilities, but you can't completely make a new or alternative language and then load it in the browser (or at least not by reimplementing ECMAScript standards... you actually can make your own language that runs within any Javascript enviroment, if you provide an interpreter or compiler that transforms it into valid JS. Some people have done something like this, eg Elm: https://elm-lang.org/).

I get it. However, the whole point of using Unions to narrow your types, ensure only a set of possible scenarios can occur, and only access data of a particular union when it’s safe to do so. That’s some of what pattern matching can provide, and 100% of what using switch statements in TypeScript with their Discriminated Unions can provide. Yes, it’s not 100% exhaustive, but TypeScript is not soundly typed, and even Elm which is still has the same issue TypeScript does: You’re running in JavaScript where anything is possible. So it’s good enough to build with and much better than what you had.

The beauty of a language like Elm (and other lambda-calculus / functional programming inspired languages) is that there's very little transformation involved in going from an idea to code. And that seems to have a big impact on getting things done.

I think the most fun and approachable way for beginners to build games with functional programming is with Elm [1].

See a few (small, demo) games built by the community in [2] .

Notice Elm has abandoned the FRP approach in favor of Model-View-Update [3].

Also check out some "compiled to JS" langs like https://elm-lang.org/.

Elm has an impressive take on how to model front-end apps and claims to avoid a whole category of issues.

Naturally I’d recommend using a better language such as ReScript or Elm or PureScript or F#‘s Fable + Elmish, but “React” is the king right now and people perceive TypeScript as “less risky” for jobs/hiring, so here we are.

Unless you want to switch to https://www.purescript.org/.

Assuming this is a PS knock, fwiw this went away a good bit ago: https://github.com/purescript/purescript/releases/tag/v0.14.2

PureScript is a Haskell-like language aimed at providing an alternative to TypeScript for statically typed programming in the JavaScript space. I highly recommend taking a look at PureScript for your compile-to-JavaScript needs outside of the use case we'll be talking about in this post.

Tons of them, but I am most interested in the following for various reasons:

PureScript[1] — been around a long time. Looks a lot like Haskell to me.

Derw[2] — Elm-like, interesting integration with Typescript

Amber[3] — smalltalk for js

Rescript[4] — its been awhile since i last looked at this project (during a catastrophic rebrand) so I'm not sure where this project is at, but it did seem very promising to me at one point.

Thinking about "tools" in a more general sense, there is Pandoc,¹ which is an end-user application, and PureScirpt,² a programming language.
