Does passing /foo/i.test not work? (Away from computer.) Perhaps it should, if it doesn't?

Most of the time, everything I want to do is check if they match a certain pattern. So what I end up writing is a RegExp that matches the pattern, and calling its test() method for every member of the array. My proposal is to allow people to use a regular expression as an argument for the three methods. Current implementations throw an error when they don't get a function as an argument, so this won't break any (working) code. An example: ["fOo","bAr"].filter(function(elem){ return /foo/i.test(elem); }); should be replaceable with ["fOo","bAr"].filter(/foo/i); For non-string members of the array, the current behavior of the RegExp.prototype.test method (ie. converting the value to a string) applies. Any reasons why this is a bad idea? (Or is it just my bad attitude? :D ) _______________________________________________ es-discuss mailing list es-discuss@mozilla.org<mailto:es-discuss@mozilla.org> https://mail.mozilla.org/listinfo/es-discuss
