On my searches, online I found that the WET principle: "Write Everything Twice" seems to be inseparable from the DRY principle: "Don't Repeat Yourself".
Can you please explain the DRY principle?
"Don't repeat yourself" (DRY) 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 the DRY principle?
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.
What is DRY design principle?
The DRY principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system". The way to achieve DRY is by creating functions and classes to make sure that any logic should be written in only one place.
What is DRY principle explain with an example?
DRY Benefits
Less code is good: It saves time and effort, is easy to maintain, and also reduces the chances of bugs. One good example of the DRY principle is the helper class in enterprise libraries, in which every piece of code is unique in the libraries and helper classes.

WHAT IS DRY principle in PHP?
The DRY Principle is one of the tenets or key concepts of programing. DRY (D-R-Y) stands for Don't Repeat Yourself. If you see yourself repeating code in the same place, for example, writing the same string over and over again, it's a good sign you can improve your programming using DRY programming techniques.
WHAT IS DRY principle in Microservices?
The premise of microservices is based on autonomous and fine-grained units of code that do one thing and one thing only. This is closely aligned with the principle of “don't repeat yourself” (DRY), which states that every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
Can DRY code be reused?
Reuse. DRY inherently promotes reuse of code because we are merging 2 or more instances of repeating code into a single block of code.
How do I stop repeating code?
To avoid the problem of duplicated bugs, never reuse code by copying and pasting existing code fragments. Instead, put it in a method if it is not already in one, so that you can call it the second time that you need it.
What's the difference between principles Yagni and kiss?
YAGNI Principle
This principle it's similar to the KISS principle, once that both of them aim for a simpler solution. The difference between them it's that YAGNI focus on removing unnecessary functionality and logic, and KISS focus on the complexity.

What are clean code principles?
A few of the broad guidelines to write clean code are: Give meaningful names to variables, functions, classes, and other entities in the code. Create functions that are small and do a single thing. Encapsulate related data and functions into small independent classes. Structure the code for better readability.
What is DRY SOLID?
The dry substance content (DS content), also called dry matter content, is the percentage of solids in a mixture of substances. The higher this proportion, the drier the mixture. The unit of DS content is [% by weight]. Dry substance content (DS content)
Should we use consistent indentation?
As you build out code, you'll inevitably end up multiple levels deep, with indented statements nested within other indented statements. For this reason, consistently applied indents are key in being able to read the code and understand the relationship between statements.
