How do you make a dry code?
Don’t Repeat Yourself (DRY) is a software development principle, the main aim of which is to reduce repetition of code. Write Everything Twice (WET) is a cheeky abbreviation to mean the opposite i.e. code that doesn’t adhere to DRY principle. It is quite obvious which one of the two should all developers be aiming for.
What are two ways to keep your code DRY?
There are several ways to keep your code DRY.
- Abstraction.
- Rule of Three.
- KISS (Keep it simple stupid!)
- Separation of Concern/ Single Responsibility.
- Single Source of Truth (SSOT)/Single Point of Truth (SPOT)
- You Aren’t Going to Need It (YAGNI)
- Try DRY Programming.
Which is not a benefit of dry code?
Readability. More often than not, DRY code is more readable. This is not because of the DRY principle itself, but rather because of the extra effort the developer put in to the code to make it follow certain principles such as DRY.
What does the DRY principle mean in code?
Many people took it [the DRY principle] to refer to code only: they thought that DRY means “don’t copy-and-paste lines of source.”. […] DRY is about the duplication of knowledge, of intent. It’s about expressing the same thing in two different places, possibly in two totally different ways.
Which is the logic side of dry ahort?
In this ahort series on DRY I’ll concentrate on the ‘logic’ side of DRY. DRY is known by other names as well: Once and Only Once, and Duplication is Evil (DIE). These are hard-coded strings that pop up at different places throughout your code: connection strings, formats, constants, like in the following code example:
Which is dry approach eliminates redundancy in editing?
A DRY approach eliminates that redundancy by using frameworks that reduce or eliminate all those editing tasks except the most important ones, leaving the extensibility of adding new knowledge variables in one place. Another approach to abstractions is the AHA principle.
Why is Aha programming assumes both wet and dry solutions?
AHA programming assumes that both WET and DRY solutions inevitably create software that is rigid and difficult to maintain.
