This server-side project was inspired by my wife.
She sent me an email of a social media post auto-generation tool that she came across called TryLately and wanted me to build it for her.
For the most part, these same projects can almost always be coded without OOP, several functions, or say, the Fetch API, but it's the use of these in the provided solutions that ultimately made me choose which were intermediate vs. beginner.
If you can do these projects as described in my summary, consider yourself intermediate in my book!
For extra practice, say if you want to become a front-end web developer, than you should also attempt to build the entire project from scratch, HTML, CSS, and all!
