I’ve used something like this in the past:
RegExp.escape = function(text) {
return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
};
It escapes some characters that do not strictly need escaping to avoid bugs in
ancient JavaScript engines. A standardized version could be even simpler, and
would indeed be very welcome IMHO.
