What are inline conditional expressions?

You can use either if statements or ternary expressions which are available in JS(and JSX in React) to conditionally execute or render expressions. Apart from these approaches, you can also embed any expressions in JSX by wrapping them in curly braces and then followed by JS logical operator &&. It is helpful to render elements conditionally within a single line and commonly used for concise logic, especially in JSX rendering.

<h1>Hello!</h1>;
{
messages.length > 0 && !isLogin ? (
<h2>You have {messages.length} unread messages.</h2>
) : (
<h2>You don't have unread messages.</h2>
);
}
