25 minutes, and no narration. It is the full cut, every chapter in order. It is still not a replacement for reading them: it shows u what happens, and the chapters are where the why is.
Every page in it is rendered by a real browser while the video plays, so when a layout moves, that is the browser doing the layout and not an animation of one. The last part builds the YouTube page from nothing, a piece at a time, and that page is Chapter 12.
If the player above stays blank, the file itself is here.
The file is served from the dev-101 Pages site rather than copied in here, so there is one video and not two. That also means it streams and seeks instead of downloading, which is the whole reason it is not read straight out of the repo.
If u want the player with the cheat sheet open beside it, that page is here.
The cheat sheet it ends on is CHEATSHEET.md here if u want to copy from it.
And if u would rather poke at a page than watch one, the playground is the same course with the code on the left and the page on the right.
