"You don't know what you don't know", so for me code-reviews were always extremely beneficial. Not only getting my code reviewed, but reviewing other's code. By getting my code reviewed, I'd be made aware of inefficiencies or improvements that I was not aware of, and by reviewing other's code, I became aware of techniques and strategies for writing better code. I think a social aspect to development is very important for improvement. Another way I have improved my coding skills in the past is to take note of things I am unfamiliar with and look them up. A key to growth is learning new things, so it's important to not ignore things that you don't know, but to actually go look them up. I often go down a rabbit hole doing this, and it takes more time, but you will learn a lot. When researching a topic or how to do something that I don't know, if I encounter something else I am unfamiliar with, I either look it up immediately (if it blocks the current problem I'm on) or I make note of It and make sure to look it up afterwards. This way you are always improving and working to fill the weaknesses in your skills/knowledge as you come across them.
