Not everything should appear at once. Conditional rendering is how you decide.

Sometimes a message should appear. Sometimes it should disappear. Sometimes a button should be red. Sometimes blue. All of this is conditional rendering — showing different UI based on what is happening in your app.

What you will build:
A login screen that starts with an input field. The user types their name. They press submit. Instantly, the input disappears and a welcome message appears: "Welcome, Sarah!"

What you will learn:
Ternary operator in JSX (the clean way to show or hide)
Multiple conditions (if this, show X; if that, show Y)
Showing loading states, error messages, and success screens
The mental model: UI that responds to state

Real-world examples:
Login screen (form → welcome message)
Loading spinner while data fetches
Error message when something goes wrong
"You have 3 items in cart" badge

Your task after this video:
Build the login screen. Then add a third state — maybe a loading message between submit and welcome. Take a screenshot of the welcome screen. Share it.

Pro tip:
Conditional rendering is what makes apps feel smart. Without it, everything is static. With it, your app responds like a conversation.
