Advanced Conditional Patterns

Let's explore more sophisticated patterns for conditional rendering in React applications.

Object Lookup Pattern

Replace complex if/else chains with object lookups:

Component Mapping

Render different components based on type:

Early Return Pattern

Simplify components with early returns:

Compound Conditions

Handle multiple conditions cleanly:

Null Rendering

Conditionally render nothing:

Exercise: Status Component

Exercise: Multi-State Component

Exercise: Permission Check

Key Takeaways

1. Object lookup - Replace long if/else chains with object maps
2. Component mapping - Use objects to map types to renderers
3. Early returns - Handle edge cases first, simplify main logic
4. Compound conditions - Order checks by priority
5. Return null - Valid way to render nothing conditionally
