What does it mean to make code DRY?
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.
Why is it important to keep code DRY?
The concept of keeping your code DRY is quite important to terraform. The ability to only mention something once reduces the possibility of introducing errors or conflicts. The DRY principle is Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
How do you avoid DRY coding?
Write unit-tests and documents smaller components to increase reusability. Keep a Clear, understandable and obvious code structure and architecture. Code reviews can help take an objective second look at how your code is built and identify duplicates and rewrites. Enforcement is a bad word, but it helps.
Is your code DRY or wet?
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.
Which is not benefits 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.
Which is not a benefit dry code?
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.
When is the DRY principle applied to a system?
When the DRY principle is applied successfully, a modification of any single element of a system does not require a change in other logically unrelated elements. Additionally, elements that are logically related all change predictably and uniformly, and are thus kept in sync.
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.
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:
