Amazon's language for storefront UI templates is Perl [1]. When I joined, I couldn't help but laugh that poor developers are dragged through the hell of 5 leetcode interviews to end up working on a UI framework that is 25 years old.

Edit: I left in 2013 so I don't know if it's still the case.

To be fair, HTML::Mason was probably the most powerful templating toolkit at the time (Text::Template was there too, but from memory Mason was almost everyone's goto).
