hi to all!
i have the following code (i stripped down the code to a short
example, but still it does reproduce the problem):
var objs = new Array();
obj = {
parameter : " "
}
objs[0] = obj;
objs[0].parameter = "apple";
objs[1] = obj;
objs[1].parameter = "banana";
alert(objs[0].parameter);
i create a json object (obj) and insert into 2 items of a previously
created array (objs[0] and objs[1]). inspecting the array, i expect
objs[0].parameter to be "apple", not "banana", which is what i keen on
getting.
any idea?

objs[0] and objs[1] are both pointers to obj. You're not creating new
instances of obj, you're creating new references to the obj object.
Define obj like this:
obj=function(){ this.parameter= "";}
and in your array, do this:
objs[0] = new obj();
objs[0].parameter = "apple";
objs[1] = new obj();
objs[1].parameter = "banana";

var objs = [

hmmm.. so a js array can store 'objectified functions' but not json objects?

A JavaScript array can hold anything. Boolean values, Objects,
Functions, numeric and string primitives, et cetera.
I don't believe there is a limit to what an array can hold, but I could
be wrong.

Welcome
As suggested i looked into JSON project and was amazed but...
What about cyclical data structures - anybody was faced it in some
project ?
Is there any satisactional recomendation...
PS i am ready to use JSON as data/object interchange when using AJAX
and my J2EE project - because it is easier to traverse the JavaScript
object than its XML representation (so of course may argue).

Hello,
I noticed that the JavaScript library for JSON posted on json.org
(http://www.json.org/json.js) is modifying Object.prototype (adding a
method - toJSONString). I thought this was considered bad practice
because it can disrupt the use of for in loops on Objects.
Am I incorrect?
Thanks,

JSON vs. XML
JSON and XML are basically used for the same purpose—to represent and interchange data. I'll try to show you why you might want to use JSON rather than XML in an AJAX context by showing you an example of how an data class (actually, a list of PHP documentation pages) might be represented, first in XML. and then in JSON. This side-by-side comparison should let you begin to understand how to represent data in JSON. The XML version:...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
