JSX Deep Dive: Conditional Rendering in React

Using if Statements Outside JSX

You can use traditional if statements before the return statement to decide what to render.

This approach keeps JSX clean and separates logic from markup.

• Define variables conditionally before JSX.
• Return different JSX based on conditions.

Ternary Operator Inside JSX

The ternary operator is a concise way to conditionally render elements inline within JSX.

It follows the syntax: condition ? expressionIfTrue : expressionIfFalse.

• Useful for simple conditional rendering.
• Keeps logic and markup together.

Logical AND (&&) Operator

The logical AND operator renders an element only if the condition is true.

If the condition is false, React ignores the expression and renders nothing.

• Ideal for rendering elements conditionally without an else case.
• Simplifies code when you only want to show something if a condition is true.

If Statement Example

Here we decide what to render before returning JSX.
