Array declaration using a variable

Question

I've this:

var tmp = "Test";

and want that:

Books.update({_id: data._id},{$set:{tmp: [0,0,0,0,0]}});

Now I get an array like this: tmp: [0,0,0,0,0] But I want that: Test [0,0,0,0,0]

Have somebody an idea how I can do that?

var tmp = "Test",
    set = {};

set[tmp] = [0,0,0,0,0];
Books.update({_id: data._id},{$set: set});
