> But I'm always worried about those situations where you dont know what you dont know. This might sound strange, but would anyone recommend any reading material or blogs for someone at my level? It's not very clear what you are asking, neither what's your background. In your situation I wouldn't spend more time learning stuff about JavaScript, I would just improve my skills in software engineering (design patterns, code quality, refactoring, etc) and diversify my knowledge (learn other languages (python, go, or some FP language to learn something really different); databases and SQL; web servers and REST; etc).
