React JSX If Statements

⚛️ React JSX If Statements (Conditional Rendering)

In React, you cannot write plain if statements inside JSX like this:

// ❌ This will NOT work


Instead, React provides several ways to handle conditions.

 1. Using Ternary Operator (Most Common)


 

export default App;

  • Syntax: condition ? trueExpression : falseExpression

  • Works perfectly for inline JSX.

 2. Using Logical AND (&&) Operator

Good for rendering something only if a condition is true.


 

  • If showMessage is false, nothing is rendered.

  • Short and clean for optional content.

 3. Using If Statements Outside JSX

You can use regular if statements before the return statement.


 

  • Useful for more complex conditions or multiple branches.

 4. Using Immediately Invoked Function Expression (IIFE) (Advanced)


 

  • Rarely used, but possible for inline complex logic.

 5. Conditional Rendering Multiple Elements


 

  • Can render multiple JSX elements using fragments <> </>.

⚡ Summary

Method Use Case Syntax
Ternary Operator Simple inline if-else condition ? expr1 : expr2
Logical AND Render if true only condition && expr
If statement outside JSX Complex logic let msg; if(...) { msg = ... }
IIFE Inline complex logic {(() => { if(...) return ... })()}

Conditional rendering is essential in React for building dynamic UIs that respond to state or props.
