What is SOLID Principles?
Five design principles that help developers write code that is easier to maintain, extend, and understand.
Why It Matters
Following SOLID principles produces code that is less likely to break when requirements change.
Real-World Example
The Single Responsibility Principle says a class should do one thing well, like handling payments, not payments and emails.
“Understanding terms like SOLID Principles matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
