Working through the original SICP (including doing ALL of the exercises!) had the largest tangible positive effect on my ability to code as someone who has a CS degree. After finishing I felt much more confident as a programmer.

I’m mainly a TS/JS node and react dev and found much of what I learned from SICP translated into a deep understanding of both, especially with regards to higher order functions, closures, state management/hooks in react etc. The subtler aspects of coding (at least in JS/TS but also generally) all kind of just started to make sense.

Would definitely recommend
