Great article and I sincerely like it. I recently started learning React and the graphical explanations in your explanation are amazing since they are so precise and unforgettable.
My only request would be to try and utilize the writing tools of this blog like the code snippets tool. I had the same issue in my first blog posts and used images to display code.
To be frank I think its purpose is to allow readers to follow your code while running the snippets which was a bit difficult for me since I had to glance back and forth between the article and my ide.
But the content is well explained. I look forward to more articles from you and have to read the rest. GREAT STUFF!
