Which principle encourages reducing code repetition?

The principle that encourages reducing code repetition is known as DRY, which stands for "Don't Repeat Yourself." This principle emphasizes the importance of abstraction and code reuse within programming practices. By following the DRY principle, developers can minimize redundancy in their codebase. When similar code segments are used in multiple places, it becomes harder to maintain and update the code. If a change is needed, it may have to be implemented in several locations, increasing the likelihood of errors.

By adhering to the DRY principle, developers create functions, classes, or modules that can be reused throughout the code, enabling easier maintenance, better organization, and clearer structure. This leads to a more efficient coding process and reduces the risk of bugs since there’s only one instance of the code to modify when changes are required.

In contrast, the other principles mentioned, such as WET (which stands for "Writing Everything Twice") encourages code duplication, KISS (Keep It Simple, Stupid) focuses on simplicity and not overcomplicating solutions, and YAGNI (You Aren't Gonna Need It) cautions against adding functionality until it is necessary. Each of these principles has its own purpose, but it is DRY that specifically addresses the issue of reducing repetition
