Print Array as comma separated list in a .each block

Question

If i have this simple block

<% p.sectors.each do |s| %>
  <%= s.name %>
<% end %>

That iterates through all of the sectors , how would i get the results to print out in a comma separated sentence, so something like this

web design, web development, Software testing

There is a method called to_sentence but is that relevant here and how do i apply this method?

Thanks

I guess you may use <%= p.sectors.map(&:to_sentence).join(', ') %> — vidang
