Does array.length = 0 free storage?

If I zero the number of elements in an array by setting its length to 0, does this also release the memory used by the pre-existing array elements?

If you are trying to release the memory used by the existing array, set the array equal to null. For example if your array had been almerger.length =100, I believe that by setting almerger = null; would effectively release that memory.

Thanks for the suggestion. I tried this:
var Araay = new Array();
Array[100] = "Y";
Araay = null;
Array[100] = "Y";

On the last statement, I get "Araay has no properties". It seems that setting the entire array to null loses its Array quality.

But it's OK, I've found that by setting each of the individual existing elements to null avoids the "out of memory" problem that happens when I try using:
Araay.length = 0

Thanks!

Another thing you could try is to create a new Array with the same name and no parameters eg

var myArray = new Array(1,2,3,4,5);
    debugPrint(myArray.length)
myArray = new Array();
    debugPrint(myArray.length) 

With regards to changing the length property that does not change the number of actual elements according to this document

Your idea seems to work fine, no memory problem, thanks! (BTW, I couldn't get the article link to work.)

The link should be working now.
