That’s mostly just an indictment of the Javascript space, not a defense of lacking fundamental knowledge.

I don’t routinely write sorting algorithms either, but I know what they are, how they differ, and how to implement them. And it’s useful knowledge - it comes up often in lots of domains.

I see lots of comments about how this is a bold stance against “imposter syndrome”, but at some point, it isn’t a syndrome. There really is basic knowledge that defines professional competence in this field, and it can’t be replaced by github stars.
