I'd used lua in my early teens to script some games and ended up receiving money for my efforts, so I put it on my resume coming out of university.

It turned out that one of the first companies (embedded, automation) I interviewed with used it for integration between various third party subsystems. I think those conversations helped me feel like less of an imposter at the time.

I never use it anymore, but the language is nice. I wonder what web development world we'd live in now if they'd embedded lua instead of creating JavaScript.
