wpAPI vs WPooW?
If you have had a good eye reading through this documentation you would have noticed that the code examples refer to wpAPI quite a bit. What is the difference between that and the WPooW library? There is none, wpAPI and WPooW are the same thing.
When I started this project I called it, what I thought at the time, best described it - an API. As it grew, I began to reflect on the name and the fact that in the WordPress community the WordPress API referred to it's restful API's. Through this process I renamed the project to WPooW (the WordPress object oriented wrapper) which I thought better represented what the library was and would not conflict with the already existing WordPress restful API.
Of course with such changes, legacy code is not always immediately replaced, hence you have this scenario. Version 2.0 will rectify this however.
I would also like to give a shout out to Alessandro Castellani and his youtube channel which helped give me an overview of what was possible in creating custom themes/plugins. Do checkout his channel for great WordPress tutorial videos.
