This is a great idea, and I think diving right into projects is a great way to learn and also helps you retain the knowledge better!
Will you be keeping the challenges available as well, as a sort of ‘side resource’? Although I’ve definitely learnt quicker with the projects, it’s been really helpful to read the explanations of certain concepts in the challenges. Perhaps something like a freeCodeCamp library with the current explanations in would be helpful for reference.
I’m still fairly early on in my learning journey, but will be keeping my eyes out for what I could contribute to with this project!
