Hi,
Apologies if I've missed something obvious, but is there any explicit
specification of how this works in Mozilla:
xs = [1, 2, 3];
xs[1] = xs;
alert(xs.join()) // prints "1,,3"
It even works when the recursion is less direct, like this:
xs = [1, 2, 3];
ys = [1, xs, 3];
xs[1] = ys;
alert(xs.join()) // prints "1,1,,3,3"
Apparently Array.toString() returns empty string if it detects it is
already inside an invocation of itself?
Best regards,
Michael
