What is the difference between conditional rendering and ternary operators in React?

Conditional rendering in React allows you to render different components or elements based on certain conditions. Ternary operators are a shorthand way to implement conditional rendering, allowing you to write concise if-else statements.

Can you give me an example of using a ternary operator for conditional rendering?

Sure! Here's an example:

const isLoggedIn = true;
return (
  <div>
    {isLoggedIn ? <h1>Welcome back!</h1> : <h1>Please log in.</h1>}
  </div>
);

This will display 'Welcome back!' if the user is logged in, otherwise it shows 'Please log in.'

Are there any downsides to using ternary operators?

Yes, while ternary operators can make code concise, they can also reduce readability if overused or nested. It's important to keep your code clear.

When should I prefer conditional rendering over ternary operators?

You should prefer conditional rendering when you have multiple conditions or complex logic that would make the code hard to read with ternary operators.
