One of the benefits with jQuery is that it just works in all older and
modern browsers (if you are using 1.9.x that is). The drawback is that you will
not the same performance as the built-in functions.
You can test $.inArray() and Array.prototype.indexOf here:

If you can use the native methods, you should do that.
And if we take a look at the ES5 support in browsers, we can see that IE 8
is the last version of IE that doesn't have full support for this (IE 9
supports everything except strict mode, which it will just ignore):

Since IE 8 is the latest version that can be installed on Windows XP, and
Microsoft is not going to support Windows XP after april this year, I guess
CouchDB shouldn't have to either.
Is it really that important to support a browser that not even Microsoft is
going to support in 1½ month?
