Elm vs PureScript: What are the differences?

What is Elm? A type inferred, functional reactive language that compiles to HTML, CSS, and JavaScript. Writing HTML apps is super easy with elm-lang/html. Not only does it render extremely fast, it also quietly guides you towards well-architected code.

What is PureScript? A strongly-typed language that compiles to Javascript. A small strongly typed programming language with expressive types that compiles to JavaScript, written in and inspired by Haskell.

Elm and PureScript are primarily classified as "Languages" and "Templating Languages & Extensions" tools respectively.

Elm and PureScript are both open source tools. It seems that PureScript with 5.86K GitHub stars and 427 forks on GitHub has more adoption than Elm with 5.3K GitHub stars and 424 GitHub forks.

What are some alternatives to Elm and PureScript?

TypeScript

TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.

React

Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

ReasonML

It lets you write simple, fast and quality type safe code while leveraging both the JavaScript & OCaml ecosystems.It is powerful, safe type inference means you rarely have to annotate types, but everything gets checked for you.

Haskell

Svelte

If you've ever built a JavaScript application, the chances are you've encountered – or at least heard of – frameworks like React, Angular, Vue and Ractive. Like Svelte, these tools all share a goal of making it easy to build slick interactive user interfaces. Rather than interpreting your application code at run time, your app is converted into ideal JavaScript at build time. That means you don't pay the performance cost of the framework's abstractions, or incur a penalty when your app first loads.
