If you get to the end of a lesson and find your version isn’t working anymore, there’s no need to panic, because we provide a download of that exact point in the course. These are available at the end of every lesson
All you have to do is download the ZIP archive, extract the contents of it, then completely replace your project folder with those contents. The reason we ask you to replace your entire folder is because there are often dot files which some operating systems hide from you.
Once you have completely replaced your project folder with the downloaded project folder, you should run
npm install to make sure all of the dependencies are installed.
Now, go back and enjoy the rest of your course material!
