Rails 3.1. How to prevent Rails to use CoffeScript?

Question

How do I prevent Rails to enable CoffeeScript and use plain JavaScript instead?

Presumably you got a good reason. Coffeescript rocks... Learning curve 0 for someone from a JS background — , May 24 '11 at 14:48

To clarify something that puzzled me (as explained in an answer to [this question](http://stackoverflow.com/questions/8722195)), the CoffeeScript gem will still get pulled into your `Gemfile.lock` if you're using other gems that require it, notably uglifier and Rails 4's Turbolinks. But commenting it out in `Gemfile` will stop the generators from creating `.js.coffee` files and they'll make `.js` files instead. – bjnord Sep 20 '13 at 00:40

Just name your files .js instead of .js.coffee. This is a Tilt naming convention. Similarly, if you don't want to use SCSS, use .css instead of .css.scss. Or if you'd rather use the Sass syntax with semantic whitespace, use .css.sass.

By default, .js.coffee files are created by certain commands (notably generate controller) as long as gem 'coffee-script' is in the Gemfile, so you'll want to comment that out.

Comment out # gem "coffee-script" in your gemfile or just use .js vs .js.coffee files
