What is the main code simplification methodology proposed by Robert Martin?

The main methodology for simplifying code proposed by Robert Martin (Uncle Bob) is the KISS principle (Keep It Simple, Stupid). It involves writing code that is as simple and understandable as possible, avoiding unnecessary complexity and optimizations. This helps improve readability, maintainability, and reduces the number of errors.

An example of applying KISS: instead of complex nested conditions, it is better to break the logic into several simple functions with clear names.
