Checkout Js2coffee! Js2coffee translates your JavaScript Code into nice, readable and valid CoffeeScript. In addition to the Js2coffee website (, there is also an NPM package available. You can install it directly from the terminal

# or globally
npm install js2coffee --g

I found this little package very handy to remove the smell from old JavaScript files and move them to more readable and maintainable CoffeeScript files.

What do you think? Is this a good solution for maintaining the old JavaScript code?
