CoffeeScript

Purpose: CoffeeScript is a language that compiles into JavaScript.
Runtime: CoffeeScript compiles to equivalent JavaScript with no interpretation at runtime.
JavaScript libraries: Existing JavaScript libraries can be used from CoffeeScript and vice versa.
Modern output: CoffeeScript 2 produces modern JavaScript syntax, including JavaScript classes and arrow functions.
Language features: CoffeeScript 2 includes async function and JSX syntax support.
Command line: The coffee command can execute scripts, compile .coffee files to .js, and provide an interactive REPL.
Source maps: The command line supports generating external or inline source maps alongside compiled JavaScript.
Node.js: The command-line utility requires Node 6 or later, while the core compiler can run in any JavaScript environment or in a browser.
Transpilation: CoffeeScript has built-in support for Babel transpilation, which requires @babel/core to be installed.
Integrations: The integrations page lists Gulp, Webpack, Grunt, and Broccoli as JavaScript build-chain tools.
Editor support: The integrations page lists CoffeeScript support for code editors including Atom, Emacs, Vim, and Visual Studio Code.
Testing integration: The integrations page lists Jest with jest-preset-coffeescript for testing.
Support: The maker directs bug reports, feature proposals, and ideas to its GitHub issues page and identifies a mailing list as a place to ask questions.
Runtime compatibility: The maker notes that JSX output always requires transpilation and that modules require Node 12 or later with type set to module in package.json.
