The Hash that prototype declares provides associative array functionality, like
returning of keys and values, stuff that Object doesn't provide on it's own.
It's intent is to act like an associative array, where Object is intended to be
used as an Object.
Contrary to my previous understanding, the Hash functions do not handle values
with type function. They still get copied around, but aren't visible from any
of the hash functions like values() or keys().
My apologies for any confusion I may have caused out there.
Cheers
P.S: If what I've said has confused you, try this example and see for yourself.
var h1 = { a: 1, b: 2 };
var h2 = { c: 3, d: function() { alert('d exists'); } };
var mergedHsh = $H(h1).merge(h2);
mergedHsh.d();
alert(mergedHsh.inspect());

There is no difference between those. They are both associative arrays
(hashes).
---------------------------------------------------
Since prototype.js has Object and Hash methods, maybe my question should
have been something like: "What is the reasoning behind why prototype
offers different properties and methods for Hash and Object types?"
