Rails syntax help

Hi Guys,

I am very new to Ruby and Rails, am trying to understand the syntax of
it. I got this code from a book but can't understand what does "</

"end.to_s" do. Here is the complete "view" code. Note: This

code works fine

<h2>A Simple Form</h2>
<%= start_form_tag(:action => "show_formdata") %>
<p>Text Field:
<%= text_field_tag("name", "Aneesha") %></p>
<p>Drop-down Selection Box:
<% languages = ["Ruby", "Java", "C#"].map do |lang|
"<option>#{lang}</option>"end.to_s %>

<%= select_tag("prog_languages[]", languages, :multiple => "true")
%></p>
<p>Checkboxes:
<%= check_box_tag("operating_systems[]", "Windows") %>Windows
<%= check_box_tag("operating_systems[]", "Linux") %>Linux
<%= check_box_tag("operating_systems[]", "Mac") %>Mac

</p>
<%= submit_tag("Submit Form") %>
<%= end_form_tag %>

This is mostly just confusingly formatted. Another way to write it
would be

<% languages = ["Ruby", "Java", "C#"].map { |lang| "<option>#{lang}</

" }.to_s %>

You're also following some very old examples - at least 2 years old.
