What is Generic Types?
A way to write flexible, reusable code that works with different data types while maintaining type safety.
Why It Matters
Generics let you write a function or component once that safely handles strings, numbers, or any other type.
Real-World Example
A generic List<T> component that can render a list of users, products, or any other type.
“Understanding terms like Generic Types 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.”
