Am I wrong?

How you fill `temp' is rather irrelevant to the solution. Suppose it
contains the results of the database query as you suggested, then you would
initialize `temp' with those results through a server-side script that
generates the constructor call or initializer literal.

However, if you are to increase efficiency, you would have the server-side
script generate the initializer appropriately using the presented algorithm
and no client-side script to filter for the maximum number of displayed
items. But then it might not even be a JS solution that is needed.

I can't change the server-side: it serves data for many different
clients (JS, Flash, other) and by changing the server-side script, you
must update all the clients. This is not possible.

Still, I do not see the second loop you are talking about. Either the
server-side script generates the client-side array, then you have one `for'
loop to iterate over it; or you retrieve the records in chunks from the
server, then you append only those to your target array that fit the
condition for almost equal distribution. The latter would require you to
know how many records there are in total, though.

I think the function presumes you have built the array temp (passed as
an argument).
I built that array inside another for loop.

I get from the server all the records, I must filter them, considered
the fact that:
1. I can show (print) a certain number of items;
2. The "unprinted" ones must represent themselves as "undefined"
elements inside an array;
3. The undefined element must appear "equally" between printed items;
There's no other specification, except for the fact that the first and
the last elements must never be undefined.
That array (temp) is very important because the rest of the program
uses it in many ways.
The fact is that the bug in the code I first posted has been
discovered late.
Thanks for your precious and patient help.
