The Valley of Code
All rights reserved © 2026
A Flavio Copes project, yes all the 1,664 lessons have been handwritten in over 8 years with passion and sweat, it's not AI slop. Claude Code estimated 5,000 hours of work to write them, that's 2.5 years 24/7.
The Valley of Code is a website whose goal is to help you become a Web Developer.
Founded by Flavio Copes.
The vision for The Valley of Code is to be a website you can always reference and use as “the place where you go learn quickly how to do X” in your day-to-day life as a developer.
