Perl first, then JavaScript.
Did you know JavaScript classes are blessed hashes?
They even take about the same amount of syntax. ("__proto__" vs "blessed", "prototype" vs "bless").
Old JavaScript made the blessing crude and obvious.
Modern JavaScript lets you hide it in a "class" decleration. Which you can also do in Perl if you want (though you'll need to choose a module for this, and people generally prefer a different approach to dressing up objects in Perl.)
There's still a blessed hash under the hood which you can see and kind of have to be aware of... in both languages.
