Conditional Rendering in React

Introduction

Conditional rendering in React refers to the ability to render different UI elements based on certain conditions. This is crucial for creating dynamic and responsive user interfaces.

Key Concepts

• React components can render different outputs based on props, state, or any other conditions.
• Commonly used techniques include logical && operator, ternary operators, and if-else statements.

Rendering Methods

1. Logical && Operator

Utilize the logical AND (&&) operator to conditionally render elements.

{condition && }
                

2. Ternary Operator

Use the ternary operator for inline conditional rendering.

{condition ?  : }
                

3. If-Else Statements

Implement if-else statements inside render methods for more complex logic.

if (condition) {
    return ;
} else {
    return ;
}
                

Best Practices

• Keep conditional rendering logic simple and readable.
• Avoid deep nesting of conditions to enhance code maintainability.
• Use separate components for different UI states when applicable.
