purescript VS rescript-compiler

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.

This is because a “Tagged Union”, another word for TypeScript’s Discriminated Union, is a way to “tag which one is in use right now… we check the tag to see”. Just like when you’re shopping and check the tag of a piece of clothing to see what the price is, what size it is, or what material it’s made out of. Languages like ReScript compile many of their Unions (called Variants) to JavaScript Objects that have a tag property.

ReScript is "Fast, Simple, Fully Typed JavaScript from the Future". Let's take a look at how we can add it to an existing React project.

REscript

Ultimately, Dhall wasn’t verbose enough nor was I Dhall ninja, but something like TypeScript or ReScript probably would have been better.

And there's rescript which is OCaml with JS friendly syntax that compiles to JS. I don't use it much, but its super impressive.

ReasonML and ReScript are a (more or less the same) new syntax on top of OCaml. ReScript only targets JS, while ReasonML targets both JS and the native archs OCaml supports. Facebook and Bloomberg are using ReScript internally, afaik. Messenger.com is written in it. Facebook also maintains React bindings to ReScript.

I've never liked OOP either, I started building sites using https://rescript-lang.org/ which is basically OCaml https://cs3110.github.io/textbook/cover.html and for me much easier to understand, all your program is in modules with an interface, you just have functions and nothing else. The code is almost always self documenting it's so easy to read once you get used to it.
