Well i sure did, this for loop code will store values of index i at their respective  negative indexes. 
Just run it. There is no problem to store and reach values at negative indexes but i want to store objects not values.

<script type="text/javascript">
var arr=[];
for (i=10;i>=-20;i--) {arr[i]=i;}
arr[-22]=-22;
for (i=10;i>=-22;i--) {document.write(arr[i],",");}
</script>

Well that was my example code for objects wasn't it?

I can see that, so how can i store them at negative indexes, i mean if i can store a value i should be able to store an object or?

I have no idea what you mean by negative keys, i want an array that stores objects starting at the integer of my choice, yes i want to start at a negative index storing my objects.

Well actually i do understand that push put a member on top of the last one, but what i need to know and what you seem unable to answer, is can i start the array at a negative index and store a value. And i answered that one myself yes no problem in javascript, if i now could get information on howto store an object that would be great and i can go on with my programming.

Yes i understand this, but it is not what i asked.

Yes i understand this, but it is not what i asked.
I even proposed ar.push('nonsense',-i) but maybe there already is similar functionality? 
If so could anyone be so kind inform me how. 
You are not the only one getting irritated, i think my question is pretty straightforward, but you seem reluctant or do not know the answer.

This is a none issue for me. I want add object at the other end -1. And i want to start create the object array as i showed in example above. From low to high or high to low really does not matter to me.

Well i proved to you that you can add an object to a negative index of the array and retrive it didn't i. How can i do the same with object.

Well i showed you it can be done, was i just lucky??????

Well i do not see how i can be any more clear if i push i add object at end of array, how and i end at start of array -1.

Maybe, your terminology confusing.
