Thanks for the great series explaining how scopes work in JS. I'm just curious what programming languages don't follow functions lexical scope pattern, but organize "containers" for variables differently?

I haven't personally worked with languages that use dynamic scope instead of lexical scope, but I read that Perl allows dynamic scope. Dynamic scope is harder to reason about because it relies on how the program runs instead of how the program is written.
