It's not clear to me what you want, since your code is wrong.

Here the correct analogous:

$ref->{foo}{$bar}

(NB: autoquoting of key "foo" !)

is

demo in the JS console

>> ref={foo: {x:42}} Object { foo: {} } >> bar="x" "x" >> ref.foo[bar] 42 >> ref['foo'][bar] 42

as a side note, $ is a legal identifier in JS so you can also write

>> $ref={foo: {x:42}} Object { foo: {} } >> $ref['foo'][$bar] 42

update

demo in the Perl debugger

DB<3> $ref = {foo=> { x => 42 } } DB<4> $bar = "x" DB<5> p $ref->{foo}{$bar} 42 DB<6> p $$ref{foo}{$bar} 42

update

DB<11> use experimental 'refaliasing'; \%ref = $ref DB<12> p $ref{foo}{$bar} 42
