What does DRY code stand for?
Don’t repeat yourself
Don’t repeat yourself (DRY, or sometimes do not repeat yourself) is a principle of software development aimed at reducing repetition of software patterns, replacing it with abstractions or using data normalization to avoid redundancy.

DRYness is achieved by good planning. As an example, say you’re hired as a technical consultant by a company that has problems with code quality and maintenance. You review the source and you see hacks and code duplication – the code is not DRY. This is a symptom of bad code quality, it’s not the reason.
What are the best practices for writing readable code?
