PureScript

PureScript is a strongly-typed, purely functional programming language that compiles to JavaScript. It is designed for robust web development, offering features like type inference, algebraic data types, and type classes, similar to Haskell. Its output is readable, efficient JavaScript code that can run in browsers or on Node.js.

Also known as: Purescript, Pure Script, PS, purs, PureScript language

Why learn PureScript?

Developers should learn PureScript when building high-assurance web applications where type safety and correctness are critical, such as in finance, healthcare, or complex front-end logic. It is ideal for those familiar with functional programming who want to leverage strong static typing and immutability to reduce runtime errors and improve maintainability in JavaScript environments.
