Here is a shorter alternative that handles non-ASCII sequences provided you 
pass in unicode:

def JSString(s):
	return repr(unicode(s))[1:]

>>> print JSString(u"\u201chi there!\u201d")
'\u201chi there!\u201d'
>>> print JSString("Hello world")
'Hello world'
>>> print JSString("Hello 'world'")
"Hello 'world'"

For ascii strings you could also use the string-escape codec, but strangely 
the unicode-escape codec doesn't escape quotes.
