Prototype.js does not set objects's constructor property properly

[navneet.krg]

create a class myClass using prototype.js's Class.create()
then create an object foo of that myClass
then "object.constructor" will return
"function Object() { [native code for Object.Object, arity=1] }"

should be myClass

does prototype.js does not set the constructor property properly

if i create the class using
function myClass(){};
foo = new myClass()
foo.constructor
will give
function myClass() {
}

Suggested new 2nd paragraph for FAQ #2.2 (updaated[1]):

If your question relates to a particular javascript library, or
conflicts between libraries, you should ask in a news group or forum
that supports the library. The clj news group will consider questions
realted to javascript within a library if no suitable answer is
provided on the library-specific forum. Make sure you include a link
to where you asked the question, or information on the responses you
received.

The ECMAScript standard does not require every object to have or inherit
a 'constructor' property. Don't be surprised if you get an unexpected
result. In this case it looks as though the prototype chain was created
by doing new Object(); , and not altered later on.

does prototype.js does not set the constructor property properly

function myClass(){};
foo = new myClass()
foo.constructor
will give
function myClass() {
}

You've forgotten to put quotes round the answer : it's the result of
calling toString on a function object.

I seriously doubt this is a link to a *newsgroup*.

NAK. That should be reworded so that the potential disadvantage of using
the particular library can be pointed out here.

NAK. I am not going to search the Web or login to a Web forum to determine
whether or not the posting is to consider. Furthermore, it is not the
newsgroup that considers it, but the subscribers of the newsgroup. And it
should be reworded ("might") so that these people are not said to be
compelled to reply.
