coffeescript VS purescript

That said, there are ways to embrace the JS ecosystem without actually using JavaScript. Many popular languages have transpilers that will convert code written in that particular language into something that will run natively in a web browser (in other words, JavaScript). Even TypeScript is a language that gets transpiled into JavaScript, so it's not that outrageous of a concept, it just gets more difficult to do the further you get away from languages that don't already look like JavaScript.

As a front-end web developer, do you still use CoffeeScript or jQuery? Unlikely, as TypeScript, ES/TC39 and Babel (and the retirement of Internet Explorer thanks to @codepo8 and his EDGE team) have helped to transform JavaScript into some kind of a modern programming language.

CoffeeScript

On the other hand, companies choose React because that's where all the developers are. If you want to build something that can be maintained years from now, you better not choose the next hype train that goes straight to nowhere (remember CoffeeScript ?). You want something battle tested that has stood the test of time, where you won't have trouble finding developers to scale once you need to. And nobody ever got fired for choosing React.

I wish for a language that combines the strengths of Haskell and Typescript. I suppose PureScript isn't that?

When I see this it makes me want to run for ReasonML/ReScript/Elm/PureScript.

Sum types (without payloads on the instances they are effectively enums) should not require a evening filling ceremonial dance event to define.

It's nice that TS is a strict super set of JS... But that's about the only reason TS is nice. Apart from that the "being a strict super set" hampers TS is a million and one ways.

To my JS is too broken to fix with a strict super set.

A web application makes use of these same ingredients, i.e. HTML, CSS, and JavaScript, but it uses significantly more JavaScript. As the JavaScript powering your web application grows in size it can bring with it a variety of problems that a few languages, like TypeScript, ReScript, PureScript, and Elm, have attempted to solve. Each of the aforementioned compile to JavaScript languages have their pros and cons but it is beyond the scope of this article to get into those details. Suffice it to say, my preference is Elm. It is also not the goal of this article to convince you to use Elm but only to show you how Elm fits into the flow of creating a web application and hosting it on GitHub Pages. So let's continue by adding Elm to our project.

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/.

PureScript[1][2] seems pretty alive these days. From my relatively small, self-contained experiments, it's a lot more flexible and expressive than Elm at the expense of (maybe?) being a bit harder to learn up-front.
