The only use of code is to process data, aka information. And any knowledge worker that the success of processing information is mostly relying on how it's organized (try operating a library without an index).

Most of the time is spent about researching what data is available and learning what data should be returned after the processing. Then you spend a bit of brain power to connect the two. The code is always trivial. I don't remember ever discussing code in the workplace since I started my career. It was always about plans (hypotheses), information (data inquiry), and specifications (especially when collaborating).

If the code is worrying you, it would be better to buy a book on whatever technology you're using and refresh your knowledge. I keep bookmarks in my web browser and have a few books on my shelf that I occasionally page through.
