Executes the ruby code within the brackets.
Prints something into erb file.
Equivalent to
<%= raw %>. Prints something verbatim (i.e. w/o escaping) into erb file. (Taken from Ruby on Rails Guides.)Avoids line break after expression.
Comments out code within brackets; not sent to client (as opposed to HTML comments).
