examples somewhere?


Curious me...

If you provide them. So far there is no `::' operator
in the JavaScript language, not even in v2.0 with classes.

Maybe you mean the namespace lookup operator of JavaScript 2.0
(with classes):

Since *you* have seen a script using the operator, *you* are to provide the
example. And no, I cannot provide one since JavaScript 2.0 as proposed by
waldemar has only one known implementation (Epimetheus) that I do not own
yet. More, ECMAScript Edition 4 is still a proposal and work on JavaScript
2.0 is still in progress. Thus I have not written any JavaScript 2.0
program yet.

I wonder if you mix up JavaScript with C(Script) here.

I found it back. It is only a colon.

<script language="JavaScript">
<!--
V1={
x:function(){
var A=prompt('First name...','');
var B=prompt('Last name...','');
alert(A + ' ' + B)}
};
V1.x()



//-->
</script>

{ x:5 }
defines a new object with a property named x, and the value of the
property is 5. Note : only works in recent browsers.

v = { x:5 };
changes the value of v to being an object with a property x, and the
value of the property is 5.

function() { ... }
defines a function object that doesn't have a personal name.

Therefore
v = { x:function() { ... } };
changes the value of v to being an object with a property, alias method,
named x, and the value of that property is a function object that can be
called by doing
v.x();

<script language="JavaScript">

V1={

var A=prompt('First name...','');
var B=prompt('Last name...','');
alert(A + ' ' + B)}
};
[...]
function() { ... }
defines a function object that doesn't have a personal name.

That is called an `anonymous function'. When you display the code
of the function, i.e. the value of the `x' property here, with IE
(6), it even shows `function anonymous() ...'.
