The Polymathic Engineer

Three fundamental software design principles help build flexible, maintainable code. The Open-Closed Principle advocates for code that's open for extension but closed for modification, using interfaces to separate varying parts from stable ones. Dependency Injection reduces coupling by providing dependencies through constructors rather than creating them internally. Inversion of Control removes responsibilities from classes by letting frameworks control application flow while your code acts as plugins. Together, these principles reduce complexity and make code easier to test, extend, and maintain.

Software Design Principles That Matter

<p>Especially with a post that explains very complicated tools to remove complexity, i want to say: Being pragmatic is probably the most important solution to manage complexity. Instead of building a very complex plugin structure, just build the obvious thing and only if it becomes clear that a plugin structure is actually needed, build it.</p>


<p>Solid post, explains solid really well</p>
