People aren't born knowledge of the programming languages at their time of birth, 65 year olds can do JavaScript just fine, it isn't even anything weird as a language :-P.

I think it is more likely that, largely, there are way more 25-34 programmers than 65+ programmers out there.

Correct, but people are more likely to learn a new skill or a tech stack in their 20s than in their 40s. And when current 65+s were in their 20s javascript wasn't a thing yet.

Not sure people over 40 don't want to learn new things; they're likely just more interested in stable long-term technologies and investing their time wisely rather than hopping onto the newest fad all the time. With age comes understanding that the more things change, the more they stay the same. Emperor's new clothes and all that.

Speaking a someone from that demographic, if one wants to keep being able to find a technical job, better keep updating those skills.
