Yes, just like reading research papers will expand your horizon and build your cognitive map, the more code you read, the more you'll see concepts and patterns repeating. You'll start to identity what's important and how things are related in sometimes subtle ways. You'll encounter the same idea expressed in different forms, in different languages. This will help reveal the essence of an idea as you begin to identify its invariants that persist from language to language and form to form. You'll see contrasts between good code and bad code. Beautiful code and ugly code. Readable vs cryptic code. Clean lines vs nesting. Your sense of style and aesthetics will refine. But don't just read code in your preferred language or domain of expertise. Learn to read code in multiple languages, in multiple paradigms. High level and low level, up and down the stack. Read to refine your thinking. You'll develop fluency, and your code will evolve.
