Leveled-up patterns for generics, conditional types, and utility types. Stop fighting the compiler and start making it work for you.
# Advanced TypeScript Types & Generics
Master advanced TypeScript type system with Google Antigravity IDE.
## Conditional Types
```typescript
type IsString<T> = T extends string ? true : false;
type ReturnType<T> = T extends (...args: any[]) => infer R ? R : never;
```
## Mapped Types
```typescript
type Optional<T> = { [K in keyof T]?: T[K] };
```
## Best Practices
- Use generics for reusable type-safe code
- Leverage mapped types for object manipulation
- Document complex types with JSDocClick the copy button to get the raw system instruction optimized for token efficiency.
Paste directly into your IDE's agent instructions or global rules file.
