What is State?
Data that a component keeps track of and can change over time
Why It Matters
State is how your app remembers things like what's in a shopping cart or whether a menu is open
Real-World Example
When you add an item to a cart, state tracks the cart contents and updates the display
“Understanding terms like State 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.”
