What is the difference between "-%>" and "%>" in Rails 3?

Question

What is the difference between :

<% @posts.each do |p| -%>
<%= p.title %>
<% end -%>

and

<% @posts.each do |p| %>
<%= p.title %>
<% end %>

and is there any ?

Looks like no. http://stackoverflow.com/questions/4407862/minus-sign-at-the-end-of-a-erb-sequence — atw13, May 14 '13 at 13:23
@atw13 Even in Rails3, `-%>` still removes trailing newlines. — kiddorails, May 14 '13 at 13:40

-%> means that do not insert '\n' and whitespaces after the command.

There is no difference.

"-%>" is completely useless in Rails 3.

you should provide a link to support that. – drewish Dec 05 '13 at 06:01
[ASCIIcasts seems to support this notion.](http://asciicasts.com/episodes/208-erb-blocks-in-rails-3) As does [this SO answer](http://stackoverflow.com/a/4407909/2540204). – neanderslob Nov 24 '14 at 23:23
