Using javascripts in a RAILS application

Question

Rails 3.2.6

It is my understanding that by having all javascripts in the /app/assets/javascripts, they are accessible to the application modules. I was following a tutorial, and at the end of application.html.erb, they added the following line:

<%= javascript_include_tag "application" %>

Is this redundant, or is there a purpose for including it at the end of application.html.erb?

Assets are not included in your views by default. That is why you have to use javascript_include_tag, stylesheet_link_tag in layout file. As to why it is added at the end - to improve page load time. more about it here

The reason for putting the javascript_include_tag at the end of the application.html.erb file is so that the content of the page is loaded first, then the javascript will be loaded. You can do it either way, but performance is better when you put the javascript_include_tag at the end.
