left, JavaScript is for now, Lisp is for life

Left one with racket (#lang sicp) instead of scheme

Depends on your learning style / motivation profile

Lisp for fundamentals, if you’re a researcher archetype or driven by thirst for knowledge or complex (beautiful) systems

Js if you want to build shit, and are the type of person who thrives on having the thing you made in your hand

JS bc you know it and this book isn't about learning a language

Scheme all the way with Dr Racket in SICP mode as editor unless you’re an Emacs pro: https://docs.racket-lang.org/sicp-manual/SICP_Language.html

The simplicity of the language is part of the magic

I'm actually pretty curious about the adaptation of this classic into Javascript.
