Julius example missing rawJS with newIdent

[jezen]

Assuming sectionClass is created with newIdent, and the generated identifier is hident2, a line like this:

$("section.#{sectionClass}").hide();

generates incorrect JavaScript like this:

$("section."hident2"").hide();

The book should be updated to mention we need to use rawJS, like this:

$("section.#{rawJS sectionClass}").hide();

Also worth mentioning that we need the necessary import too.

import           Text.Julius          (RawJS (..))

Page that should be updated is here.
