A simple example about CouchJS in user space, such as with a browser?

Definitions

CouchJs : JavaScript interpreter for CouchDB

     

CouchDB : NonSQL db, where you do most of the things in user space with things like JS, because at the database level it's usually expensive

     

Integrity : with information security, integrity means that data cannot be changed unnoticed. More details here .

The CouchJS website has no internal search, and after you come across more or less confusing blogs, I get lost. Where can I find some simple examples (and not just curls / telnets), for example below?

<script type="text/javascript" src="lib/jquery-1.7.2.js"></script>
<script type="text/javascript" src="lib/jquery-ui-1.8.21.custom.min.js"></script>
<script src="http://127.0.0.1:5984/_utils/script/jquery.couch.js"></script>
    //# 1. initilalize the db -object
    //# 2. save something to the db with the object
<script> db.test.save('hello world') </script>

Perhaps useful for other newbies.
