About this resource
About & credits
Return to Code is an independent, self-paced learning resource for engineers. Lessons, checks, and practice help you develop and review your understanding.
Created with AI assistance
Erick developed Return to Code with AI tools, including OpenAI Codex, to draft and revise lessons, examples, concept checks, and the website. The course began with his own study request and evolved through iterative feedback and testing.
Erick sets the direction and takes responsibility for what is published. AI-assisted content can contain errors; the course does not claim independent expert review of every lesson. Use the linked sources to explore a topic further, and use Give feedback to report an error or unclear explanation.
