Introduction: What is a Design Pattern?
What is one of the most important aspects of writing maintainable code?
Why is managing written code so much more complicated than writing maintainable design patterns?
What does the acronym GoF stand for?
Why is it important to understand patterns and be familiar with them?
What are the three main benefits of design patterns?
- Design patterns are proven solutions: They provide solid approaches to solving problems in software development by using proven techniques that reflect the insights of the developers who helped create the pattern.
- You can reuse design patterns: Most are out-of-the-box solutions adapted to suit our own needs, so they are pretty robust.
- Patterns can be expressive: The structure and vocabulary of the design pattern we are looking at can help us express rather large solutions quite elegantly.
Are design patterns an exact solution?
Can you explain one of the advantages of using design patterns?
Design patterns assist in preventing minor issues that can cause significant problems in the application development process. Code built on proven practices allows us to spend less time worrying about the structure of our code and more time focusing on quality solutions. Using patterns, we can code in a more structured and organized way, reducing the necessity of refactoring it later.
Patterns enable generalized solutions to describe without being explicit about their application to a specific problem. Due to this generalized approach, we can use design patterns to improve the structure of our code regardless of the application (and, in many cases, the programming language) we are using.
Specific patterns can decrease the overall file-size footprint of our code by avoiding repetition. Encouraging developers to look at their solutions closely can help reduce duplication. To reduce the overall size of our codebase, we can reduce the number of functions performing similar tasks in favor of a single generalized higher-order function. We should use an approach known as DRY coding. DRY coding is an approach that aims to make our code more readable.
Patterns expand a developer's vocabulary, which makes communication faster.
Frequently used design patterns are improved over time by harnessing the knowledge of the many. Using design patterns gives back to the design pattern community and helps improve application development. In some cases, this leads to creating entirely new design patterns, while in others, it can lead to improved guidelines. This approach can ensure that pattern-based solutions continue to become more robust than ad-hoc solutions may be.
