What will be result if array contains properties which values:
var arr = [NaN, Infinity, -Infinity];
NaN and Infinity ares primitive values of Number Type.
And, where is wrong in explicit loop algorithm?

Re: Does string contain A, and if so, does a section of string contain B

TIMTOWTDI.
Don't be a douche. I'd never seen the switch followed by .test, and
really have never used a switch in Javascript, so I didn't catch that
this is what that was. Sue me.
I looked into that before posting, but I'm not sure that (a) I'm doing
it right, and (b) it's going to do what I'm needing.

st...@nonspam.com (Steel) — Mon, 12 Dec 2009 07:57:04 UT

Hi at all

function cooks()
{
var cookieEnabled=(navigator.cooki eEnabled)? true : false
//if not IE4+ nor NS6+
if (typeof navigator.cookieEnabled=="unde fined" && !cookieEnabled){
document.cookie="testcookie"
cookieEnabled=(document.cookie .indexOf("testcookie")!=-1)? true : false

Should change "current" to "the most widely supported".
Also, the entry mentions JScript versions 5.0 and 5.5 and JavaScriptTM
versions 1.3 and 1.5.
Instead, it should not mention multiple versions of the same
implementation; just the base version.
Of course.
Pity poor JScript 5.8 (in IE8) still doesn't support the *third* edition

Re: Reading files inside zip files from Javascript

If you are using Ajax then you are calling a server side process. Do it on
the server. Zip is fully supported by server side things such as PHP.

Try using document.title.
That will work in more browsers. I don't know the specifics of the
scenario here, but it probably has something to do with your lixcheck thing.
I see you posed the argument that intelligent user will have a choice of
browser.
And so the implication that if the user does not have a choice, he must

Think about that a little more. Why would the condition return true?

I presume this can be done better in Perl, too.
That is not equivalent to what you are doing in Perl above, though.
Incidentally, you should not assume people know other languages than those
discussed in the target newsgroup, although it is often the case. When in
doubt, explain what the code in the other language does.

Thanks, I had actually come up with the following not too long ago:
var arr = [1, 2, 3, "a", "b", "c", 4, 5, 6];
var result = arr.reduce(function(a,b){
if(!a)
return [b];
if(typeof b === "number"){
if(typeof a[a.length - 1] === "number")
a[a.length - 1] += b;
else

I guess you mean the first part of the question is correct. Here's a
full example, I've added alerts to show what's happening. It can be
written in less code, but that is not a good reason of itself to do
that.
The function should probably be defined separately to make maintenance
