How to replace CoffeeScript with JavaScript in Rails application?

[dongtong]

Sometimes, we don't want to use CoffeeScript engine in Rails application, we want to use JavaScript engine, How do that?

Edit application config in config/application.rb

class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1
    # replace coffeescript with js
    config.generators.javascript_engine :js
end
