Anecdote time:
A long time ago I was put on a javascript project. It was a greenfield one but I had to use js because it was a browser app.
I've also heard this Scheme myth but having worked with Common Lisp I thought that this must be a mistake.
So I took a look at JSON and thought that well json is homoiconic. The problem is that you don't have a homoiconic syntax for functions so I tried the eval way but it became ovbious tha this is an ugly hack at best. I concluded that js has anything to do with scheme.
