What is DRY Development?

DRY, which stands for ‘don’t repeat yourself,’ is a principle of software development that aims at reducing the repetition of patterns and code duplication in favor of abstractions and avoiding redundancy.

Popularized by the book, The Pragmatic Programmer, the DRY principle states that, “every piece of knowledge must have a single, unambiguous, authoritative representation within a system.” Using the principle, logic or algorithms that have certain functionality should only appear once in an application.
