We go through material so fast at The Iron Yard.
It isn’t like we go through things too fast, but just fast enough to understand everything. I personally have a tendency to forget basic syntax when blazing through new material.
Do I put a semi-colon here or wrap it in quotation marks?
Do I need curly brackets here?
Little details like that come up often in my brain. I find it helpful to try to not remember the exact syntax, but where I wrote code similar to that to reference. That way I’m not trying to rush and memorize specific syntax, but over time as I continuously refer to my own work it will become more normal.

Personally, I enjoy looking at code that I have wrote before. Especially code that I don’t remember. I can see my progress and have the “what was I thinking when I wrote this?” moments. To be able to mock my previous self is crucial in self evolution. See what I did, and make it better. Then I’m not just referencing some article online, but take something that I put time into and make a new reference by upgrading it. There is always something to do. Code can always be smaller, faster, and more efficient. It’s my job to find a perfect balance between those and the time it takes to write the code.
