Yeah, I don't like the comparisons of JS to Lisp, because I think they mostly center on the existance of the map and filter methods of Array. To me, that's just not what Lisp is about. C# has map/filter/etc, and we don't say C# is-a Lisp.

And there are many other such features that were once unique/unique-ish to Lisp, that were major selling points for using Lisp at the time, but are now pretty common across a very diverse set of languages. Garbage collection being one. Higher order functions being another.

Lisp's big idea that stuck to being unique to Lisp is homoiconicity. It's the one thing that continues to be valuable enough to warrant using Lisp, despite everything else that has been stolen and copied.

Of course, not that I ever used Common Lisp, and not that I use Racket anymore. I enjoyed the hell out of programming in Racket. Up until the point I needed to access a database. Man, who's got time for that Jankasarous Rex? But I really would love a homoiconic language for the .NET CLR. That would be pretty sweet.

Well put.
