Why does that matter? You are not going to get paid to work through the SICP exercises on a job. Rather, you are going to use the things you learned through SICP on a job. Like deciding when JavaScript is the right tool and when it isn't.
If learning a new language and syntax is a barrier, you will not be able to follow SICP anyway, since it includes developing multiple languages in various paradigms.
Come on, I'm not putting anybody down. Just pointing out that you cannot avoid learning new languages anyway, since the exercises in the book requires you to design multiple different languages. It is basically a book about language design.
