Rendering Components Conditionally in React
Conditional rendering in React allows us to display different components or results based on certain conditions. A handy way to achieve this is by using the ternary operator.
The ternary operator is a one-line shortcut for the if-else
statement. It checks a condition and returns a value based on whether the condition is true
or false
.
Here is a simple example:
const App = () => {
const isUserLoggedIn = true;
return (
<div>
{isUserLoggedIn ? <LogoutButton /> : <LoginButton />}
</div>
);
};
In this example, if isUserLoggedIn
is true
, <LogoutButton />
is rendered, otherwise <LoginButton />
is rendered. This allows us to conditionally render components in a clean and concise way.
Remember that the condition should always return a boolean (true
or false
) for the ternary operator to work properly.
Mastering conditional rendering techniques such as these will allow you to create more dynamic and interactive user interfaces in React.
Happy coding!
