eRuby (Embedded Ruby) is a templating system that embeds Ruby into a text document. It is often used to embed Ruby code in an HTML document, similar to ASP, JSP and PHP. The templating system of eRuby combines the ruby code and the plain text to provide flow control and variable substitution, thus making it easy to maintain.The View module of the rails is responsible to display the response or output on a browser.
