Over the weekend I attended a session on JavaScript at the No Fluff
Just Stuff conference and learned an interesting quirk that I wanted to
ask a question about..
Take this code:
x = 5;
function foo() {
alert(x);
var x = 10;
alert(x);
}
foo();
The first alert will display 'undefined', and the second will display
10. Apparently JavaScript recognizes the 'var x = 10' declaration
inside foo() even before that line is reached - it spots the
declaration, but not the initialization to 10. Only after x is set to
10 and the second alert is reached will the 10 be displayed.
My question is... is there any way from this code to access the global
x variable (5) from within foo()?

No, it is not.
Name a browser where it is not true.
Note: I didn't say it is _required_ to be true. I said it _is_ always true.
And will continue to be.

For example, any browser showing an SVG document using Adobe SVG Viewer
(ASV). Tell me, how many times do you need to be told before you will
accept that? Twenty? A hundred?
Note: I didn't say it is _required_ to be true.
Which would have been only equally false.
I said it _is_ always true.
But it is not.
And will continue to be.
Therefore, it will not.

The context of that is the ASV, not a browser. That the ASV happens
to run as a plugin in a browser does not change that.

That's the plugin you are referencing, not the browser. Now, how many
times do you need that pointed out to *you* before you accept it?
Twenty? A hundred?

VARIABLE SCOPE IN JAVASCRIPT

First off, what the heck is 'scope' (the kind that doesn't help kill the germs that cause bad breath)? Scope describes the context in which a variable can be used. For example, if a variable's scope is a certain function, then that variable can only be used in that function. If you were to try to access that variable anywhere else in...

Python doesn't like when you read a variable that exists in an outer

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.
