By the way, I read SICP and it's one of my favorite book. It's unbelievable how quick things are hacked... i.e. 2 pages and you've got a SQL-like language. Also, I must agree that Scheme really fit with the theme and the book. It's clean, it's concise, there's no funky syntax to learn. And, I also must agree that the interpreter and compiler parts would be much much more complex in JS.

All that being said, I still think lots of great concepts behind SICP can be explained with JS as the main language instead of scheme. If it can help some people to feel at home and quick the book, that's just great. They'll most likely like it and then read the real SICP for the other parts.

Lastly, I must agree that when I read SICP the first time, it was also to learn scheme as a side-effect. But it's not necessarily everyone.
