React Conditional Rendering
⚛️ React Conditional Rendering
In React, you can conditionally render JSX using:
✔ if statements
✔ ternary operator
✔ logical AND (&&)
✔ switch statements
✔ conditional return
1. Using if Statement (Outside JSX)
This completely returns different UI depending on the condition.
2. Using Ternary Operator (Inline Condition)
Useful for short, simple conditions.
3. Using Logical AND (&&)
Used when you want to show something only if a condition is true.
If isAdmin is true, then the button will render.
4. Using if...else Inside JSX (Not Allowed)
❌ You cannot use if inside JSX:
✔ Use conditional expressions instead.
5. Conditional Component Rendering
6. Switch Case (Multiple Conditions)
7. Conditional CSS Rendering
