join(...) public

Returns a string created by converting each element of the array to a string, separated by sep.

   [ "a", "b", "c" ].join        #=> "abc"
   [ "a", "b", "c" ].join("-")   #=> "a-b-c"

I use this in views when I need to join a array of objects from a sql request here is a basic version of what I mean.

Code example

<%= @blogs.map{ |blog| blog.comment }.join(“ | ”) %>
