# When inserting Javascript in HTML there is a a problem with the
# </script> end tag.
# 
# Standard Javascript escaping works fine for most strings, but the 
# browser interprets </script> before Javascript is being parsed, so 
# it needs to be HTML escaped while the browser is parsing, and then
# unescaped as Javascript parses it.

# Regular to_json
{ 'key' => '</script>' }.to_json
