Embedded Ruby (ERB) is a templating system that lets you write HTML with Ruby code embedded within. ERB helpers are methods that simplify common tasks in views. Here are a few examples:

1. Create a link:

   <%= link_to "Link Text", path %>
   

2. Display error messages:

   <% @object.errors.full_messages.each do |message| %>
     <div><%= message %></div>
   <% end %>
