WET (Write Everything Twice) Perils:

1. Maintenance Nightmare: With duplicated code, any change needs to be replicated across all instances. This makes maintenance cumbersome and error-prone.

2. Bug Propagation: If a bug exists in a duplicated code segment, it’s likely present everywhere the code is replicated. This can lead to widespread system vulnerabilities.

3. Increased Complexity: WET code often leads to bloated, complex systems that are hard to understand and navigate, making it challenging for new developers to onboard.

4. Scalability Issues: As the system grows, so does the duplicated code, leading to heavier, less manageable, and slower applications.

5. Inconsistency Risks: It’s easy to update one instance of the code and miss others, leading to inconsistent behavior across the application.

6. Poor Optimization: Duplicate code makes it harder to implement optimizations. Changes meant to improve performance must be applied in multiple places, increasing the risk of missing some.
