Conditional rendering is a technique that allows you to render different components or content based on certain conditions.
You can use if statements, ternary operators, or logical && operators.
Conditional rendering is essential for creating dynamic user interfaces that respond to user input, application state, or other conditions.
function Greeting({ isLoggedIn }) { if (isLoggedIn) { return <h1>Welcome back!</h1>; } return <h1>Please sign in.</h1>; }
// Using ternary operator function Greeting({ isLoggedIn }) { return ( <div> {isLoggedIn ? <h1>Welcome back!</h1> : <h1>Please sign in.</h1>} </div> ); }
