Reusable design for writing code that provides a well-defined function
In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code.
Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase the quality of the resulting program.
Notably, a pattern does not consist of a software artifact. Most development resources that a programmer uses involve configuring the codebase to use an artifact such as a library (to name just one example). In contrast, to use a pattern, a programmer writes code as described by the pattern. The result is unique every time even though the result may be recognizable as based on the pattern.
Some consider using patterns to be best practice for software design.
Some consider using design patterns as a structured approach to computer programming.
Conceptually, design pattern may be described as more specific than programming paradigm and less specific than algorithm.
