Up to this point - the page has 6.6k lines of codes. Considering this is the average number of codes in a single WF page, then WF have 1,400,000 X 6.6K = 9.24 Billions lines of code.
I wouldn't say rendered HTML counts as code in this context.
- the script this page runs on is a template - the same one that is used for every other page like it
- there is a loop that renders each post; the same code is not repeated for every single post
- the content of each post is saved in the database and isn't code; there's a function that renders it.
