S.O.L.I.D. Principles
The SOLID principles are a set of five foundational object-oriented design guidelines that help developers build software systems that are maintainable, scalable, and resilient to change.
Introduced and popularized by Robert C. Martin, SOLID emphasizes designing classes and modules with clear responsibilities, low coupling, and high cohesion.
Rather than focusing on syntax or specific technologies, these principles guide how software components should interact and evolve over time. By applying SOLID, developers reduce the risk of fragile code, make systems easier to understand and test, and ensure that future enhancements can be introduced with minimal impact on existing functionality.
In essence, SOLID is not about writing more code—it is about writing better-structured code that stands the test of time.
