Conditional rendering in React: The Ultimate Guide | By Devshefali | March 2025

The conditional rendering in React allows you to display various user interface elements according to the conditions. This is useful for managing authentication states, user authorizations, loading states, etc.

Just as JavaScript provides If-Else, Ternary (? :), Logical and (&&) and Switch-Case, React also uses these methods to make components conditionally.

In this article, you will discover all these techniques, their best use cases and best practices.

Conditional rendering means changing the user interface according to a condition.

For example, if a user is connected, display a welcome message; Otherwise, display a connection prompt.

function UserGreeting({ isLoggedIn }) {
if (isLoggedIn) {
return <h2>Welcome, User!</h2>;
} else {
return <h2>Please Login!</h2>;
}
}

In React applications, the user interface must change depending on different situations, such as user actions or data availability. The conditional rendering helps to display or hide elements according to these conditions, which makes the application more interactive and user -friendly.

Here are some current examples:

Authentication – View connection / registration to the guests and a dashboard for connected users.
Loading states – Display a loading spinner while recovering data.
User roles – Display different content for administrators, publishers or guests.
Error management – Show error messages when something is wrong.
Tilting features – Activate or deactivate the features dynamically.

You can write a more cleaning and readable code using the right conditional rendering technique and also improve the user experience.
