Hi all,
Does anyone know of a way in IE to determine the prototype name of an
object?
For instance, in Mozilla, I can say:
junk = document.getElementById("myID");
alert(junk.toString());

i wrote this sample code:

One of the complaints about prototype.js (google for it if you're not
familiar with it) is that it's poorly documented. I have this inkling
that the key to understanding prototype.js is in the bind function.
The problem with Javascript is that the "this" operator is poorly
overloaded and it is often hard to understand in the context of
object-oriented javascript
So, let's start with the definition:

Hi all,
What I am trying to achieve is an 'inherits' method similar to Douglas
Crockford's (http://www.crockford.com/javascript/inheritance.html) but
that can enable access to the superclass' priviledged methods also. Do
you know if this is possible ?
In the following example, I create an ObjectA (variable a), an ObjectB
which inherits ObjectA (variable b) and an ObjectC which inherits
ObjectA (variable c1). The 'toString ()' method...

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,

I wrote a .repeat(n) function for strings which seemed to work fine:
String.prototype.repeat = function(n) {
// repeats the string n times
if (n<1) return "";
if (n<2) return this;
for (var aStr = ;--n>0;) aStr.push(aStr);
return aStr.join("");
}

I've heard that JavaScript is a prototype-based language instead of a
class based one. I'm interested in learning the prototype-based
paradigm of OO programming, but I am unsure of the best way to use
JavaScript as a prototype-based language. I'm stuck between two ways
and both methods might be right (or wrong).
Method 1:
/* create an Animal "object" */
function Animal() {} ;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
