Что и зачем

Что такое Reason?

Reason is a programming language powered by OCaml's strong type system, and has a syntax designed to feel familiar to people coming from JavaScript or C-family languages.

Примечание: Reason можно перевести на OСaml и обратно с помощью команды refmt. Что можно на Reason также возможно на OСaml и обратно.

Зачем использовать Reason?

Сильная система типов лежащая на основе Reason поможет уменьшить количество багов, увеличит производительность и увеличит возможности рефакторинга вашего кода.

Различные окружения

Проекты позволяющие использовать Reason (и OCaml) в различных окружениях:

  • Native Executables: Using the standard compiler native executables can be built and run directly on your machine.
  • Браузеры: There are several projects that will compile Reason to equivalent JavaScript code that can be run in the browser.

Альтернативы

Here are some alternatives that share similar concepts with Reason:

  • Rust. Inspired by the ML family of languages, but not garbage collected. Has excellent parallelism support.
  • Elm. Another great language in the ML family. Focuses on building web applications. See the widely praised talk on Elm, Let's Be Mainstream.
  • PureScript. Inspired by Haskell, compiles to the JavaScript.
  • Fable. Based on F#, which is closely related to OCaml.
  • ClojureScript. Dynamically typed language that prioritizes simplicity & great interop.
  • Swift. Language built by Apple, and interoperates with Objective-C well.
  • Haxe. Compiles to basically anything with a focus on game development.
