Question

I have just started learning Rails, is it required for me to learn CoffeeScript as well? Where it becomes useful?

Answer 1

You do not need to know coffeescript to learn rails. While Coffeescript is the default as of rails 3.1 you can change it to use pure javascript instead. To do so:

1. Comment out gem “coffee-script” in your Gemfile
2. Use .js instead of .js.coffee for your javascript files
