Check out The Impostor's Handbook: 2-parts on various CS concepts in human-readable language.

Also, I'd look into modern practices around the tech stack / programming language of your choice: code linters, debug tools, static analysis tools, refactoring tools, various command line tools, build/packagement tools, etc.

Also familiarize yourself with the CI/CD tools/approaches in your field.

Lastly, find one or more opensource projects with decent QA practices and start contributing to get into the habit of following prescribed tools, code standards, automated testing, etc.

Good luck.

This book looks very neat. I don't know JS, but I will try to go through it. Thanks for sharing!
