in reply to using ref to hash of hash effectively

It's not clear for me what you want and all those typos don't help make it clearer.

The following example should get you started

It shows how to iterate easily thru a nested HoH

use strict; use warnings; use 5.10.0; my $weapons_ref = { dagger => { cost => 8, damage => 4, armor => 0 }, shortsword => { cost => 10, damage => 5, armor => 0 }, warhammer => { cost => 25, damage => 6, armor => 0 }, longsword => { cost => 40, damage => 7, armor => 0 }, greataxe => { cost => 74, damage => 8, armor => 0 }, }; while ( my ($k1, $v1) = each %$weapons_ref ){ while ( my ($k2, $v2) = each %$v1 ){ say "$k1 $k2 $v2"; } }

I'd love to see your "easy" JS code tho! ;-)
