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.

Example from Wikipedia:

class ERBExample
    attr_accessor:variable1
    
    # using bind to access class variables
    def render()
        renderer.result(binding)
    end

    def initialize(variable1)
        @variable1 = variable1
    end

    # Expose private binding() method.
    def get_binding
        binding()
    end
end

example = ERBExample.new(variable1)
renderer = ERB.new(template)
puts output = renderer.result(example.get_binding)
