Is it possible for an expression to iteratively build numbered arrays via loop?

[Dan Ebberts]

What is it you’re trying to do exactly? It’s hard to tell from your description if you’re running into one of the inherent limitations of expressions (no persistent variables, no way to share data outside the expression except by manipulating the value of the property hosting the expression, etc.)

Thanks for the quick reply, Dan. I can’t tell you how many of your previous posts have been the Google result that helped me out with something.

Anyway, what I’d love to have happen is something like this:

numArrays = [some number];
defaultArrayName = “arrayNumber”;

for(i = 0; i < numArrays; i++){
var (defaultArrayName + i) = new Array();
}

Obviously what I’ve written above doesn’t work, but hopefully it communicates the idea: a loop that makes numbered arrays. Thoughts?

(To be clear: within the context of a single expression, I need a bunch of arrays.)

The closest I can think of would be to create an array of arrays:

myArray = [];
numArrays = 5;

for(i = 0; i < numArrays; i++){
myArray[i] = [];
}

They wouldn’t be named, but you could access them easily by index.
