In ReactJS, you can use conditionals to render different components or elements based on certain conditions. React provides several ways to handle conditional rendering using JavaScript expressions.

✅ 1. Using if-else Statements

You can use a standard if-else statement to render content conditionally.

Example:

jsx
<h1>{isLoggedIn ? 'Welcome back!' : 'Please sign in.'}<div>    <p>Loading...<h1>Welcome to your profile!<h1>Please log in to continue.<div>    {isLoggedIn ? <UserProfile /> : <LoginPrompt />}  </div>);export default App;

• Components like <UserProfile /> and <LoginPrompt /> are conditionally rendered.

✅ Which to Use?

• Use if-else for complex logic.

• Use Ternary Operator for short, simple conditions.

• Use Logical && if rendering is based on a single true/false condition.

• Use Switch for multiple choices.
