Speaking of functions. The function.php was lost to me in the first week of working on this project but as time past I came to understand it and its purpose as a place to store your functions. For me the power of function.php was not having to be too pressured when using certain variables and the WordPress functions at least when used with in "The Loop".
The Loop is a term that refers to the while loop that is used in WordPress to generate posts. This loop allows creators to use functions that, within which, automatically refer to the singular post. Functions created in the function.php will benefit from this and as I keep on working I began to realize that I was writing way "code" less out in the other php pages.
Finally the reality of how well a CMS WordPress was didn't resonate until I have created quite a few test posts and saw how well things were stored and how the information was referenced inside the MySQL database. Having said that I must say that CMS aren't always the go to solution they claim to be. While the power of WordPress was evident to me its not for everyone's site. Brochure type sites don't need anything beyond HTML5 and Javasript. They simply need to give minimal interactivity and support of media. WordPress is for site where content is a concern. Where information, media and how the visitor consumes it is very important.
