1. Using if Statements
The simplest way to implement conditional rendering is by using traditional if statements before returning JSX.
// Example: Using if statement for conditional rendering function UserGreeting({ isLoggedIn }) { if (isLoggedIn) { return <h2>Welcome Back!</h2>; } return <h2>Please Log In</h2>; }
2. Using Ternary Operator
The ternary operator is widely used for short inline conditional rendering. It helps simplify conditions directly within the JSX.
// Example: Using Ternary Operator function Greeting({ isMorning }) { return ( <h3> {isMorning ? 'Good Morning!' : 'Good Evening!'} </h3> ); }
3. Using Logical AND (&&) Operator
When you only want to show an element if a condition is true, the logical AND operator is a great option.
// Example: Using Logical AND Operator function Notification({ show }) { return ( <div> {show && <p>You have new messages!</p>} </div> ); }
4. Conditional Rendering with Functions
You can use helper functions to simplify conditional rendering when logic becomes complex.
// Example: Conditional Rendering using Function function Dashboard({ role }) { function getDashboard() { if (role === 'admin') { return <p>Welcome, Admin!</p>; } else { return <p>Welcome, User!</p>; } } return <div>{getDashboard()}</div>; }
💡 Real-Time Benefits
Conditional rendering enhances **user experience** by showing only relevant components at the right time. It helps React apps feel interactive, reduces clutter, and improves performance by avoiding unnecessary renders.
Pro Tip: Always ensure that conditions return valid JSX or
null to prevent runtime errors.
