Disable AI suggestions while you learn
This course teaches you to hand-write every line of code. Open VS Code (or your editor of choice) and turn off Copilot, Cursor Tab, Tabnine, Codeium, and any inline AI autocomplete before you start a lesson.
AI mid-completion robs you of the small mistakes that make concepts stick. You'll be a faster, more independent developer at the end of the course if you type every character yourself. Re-enable AI for your real work after â never during a lesson.
Goal of this course: learn, not ship fastest.
