Yeah, the same way everything worthwhile about spring water can be found in mud.

Extending the JavaScript grammar into a domain-specific language, and then generating conforming code to run, almost requires adding Babel.js to your build and then doing a lot more work than writing a Lisp macro. Most devs probably never will.

Not homoiconicity and macros. And in the case of TypeScript, not interactivity.

Besides that, Mrs. Lincoln, how did you enjoy the play?
