coffeescript Getting started with coffeescript Hello Word (Linux and OS X)


Example

CoffeeScript is a scripting language that compiles into JavaScript. Any code written in CoffeeScript can be translated into JavaScript with a one-to-one matching.

CoffeeScript can be easily installed with npm:

$ mkdir coffee && cd coffee
$ npm install -g coffee-script

The -g flag will install CoffeeScript globally, so it will always be available on your CLI. Don't use the -g flag if you want a local installation:

$ mkdir coffee && cd coffee
$ npm install coffee-script

When the package is installed, create a helloword.coffee file in the working directory and write some CoffeeScript code in it.

console.log 'Hello word!'

This code can be executed by calling the CoffeeScript binary. If you installed CoffeeScript globally, simply run:

$ coffee helloword.coffee

If you installed CoffeeScript locally, you will find the binary in the installation folder:

$ ./node_modules/coffee-script/bin/coffee helloword.coffee

In both cases, the result will be printed in the console: Hello word!
